SSD free space is not seen by MacBook Pro

This information appears completely normal. It would be helpful to see what the permissions settings are, but you can't show them if you cannot boot properly.

Are you able to boot from this drive? What version of macOS was on the drive you cloned? I would suggest you might work through the following:

A Troubleshooting Procedure that may Fix Problems with macOS El Capitan or Later

You should try each, one at a time, then test to see if the problem is fixed before going on to the next.

Be sure to backup your files before proceeding if possible.

1. Shutdown the computer, wait 30 seconds, restart the computer.
2. Disconnect all third-party peripherals and remove any support software like drivers and plug-ins.
3. Resetting your Mac’s PRAM and NVRAM
4. Reset the System Management Controller (SMC)
5. Start the computer in Safe Mode, then restart normally. This is slower than a standard startup.
6. Repair the disk by booting from the Recovery HD. Immediately after the chime hold down the Command and R keys until the Utility Menu appears. Choose Disk Utility and click on the Continue button. Select the indented (usually, Macintosh HD) volume entry from the side list. Click on the First Aid button in the toolbar. Wait for the Done button to appear. Quit Disk Utility and return to the Utility Menu. Restart the computer from the Apple Menu.
7. Create a New User Account Open Users & Groups preferences. Click on the lock icon and enter your Admin password when prompted. On the left under Current User click on the Add [+] button under Login Options. Setup a new Admin user account. Upon completion log out of your current account then log into the new account. If your problems cease, then consider switching to the new account and transferring your files to it - Transferring files from one User Account to another.
8. Download and install the OS X El Capitan 10.11.6 Combo Update or 10.12.6 Combo Update or Download macOS High Sierra 10.13.3 Combo Update as needed.
9. Reinstall OS X by booting from the Recovery HD using the Command and R keys. When the Utility Menu appears select Reinstall OS X then click on the Continue button.
10. Erase and Install OS X Restart the computer. Immediately after the chime hold down the Command and R keys until the Apple logo appears. When the Utility Menu appears:

1. Select Disk Utility from the Utility Menu and click on Continue button.
2. When Disk Utility loads select the drive (out-dented entry) from the Device list.
3. Click on the Erase icon in Disk Utility's toolbar. A panel will drop down.
4. Set the Format type to Mac OS Extended (Journaled.)
5. Click on the Apply button, then wait for the Done button to activate and click on it.
6. Quit Disk Utility and return to the Utility Menu.
7. Select Reinstall OS X and click on the Continue button.

Sorry, I didn't see this as I was prepping a post of my own. Thanks for the added information. Still would like the disk's permissions. Normally, they should be:

Owner = System - read/write

Group = Admin or wheel - read only

Everyone - read only

The bottom of the Get Info window contains:

It already is partitioned - one partition the full size of the disk. It appears to be formatted properly. I'm not sure of why you are having a problem. You say you cloned something. What did you clone and from where? Also what tool did you use for cloning? Press Command-I to open the Get Info window. The topmost panel will provide proper disk information: Capacity, User, and Available space. The bottom-most panel will have disk permissions information: User, Group, and Everyone. I'd like to know what those are. Or you can take a screenshot of the entire dialog and paste it in your reply.

To Post A Screen Shot

1. Press Command-Shift-4 which will change the cursor to crosshairs.
2. Hold down the mouse button and use the crosshairs to select the part of the screen you wish to capture.
3. Release the mouse button and the image will be saved to your Desktop.
4. Drag the pic into your open forum editor. If that fails then go to the following steps.
5. Click on the Camera icon in the toolbar of the forum message editor.
6. Drag the image onto the Choose File button and click on the Insert button.

How is the SSD configured? It should be using GUID and formatted Mac OS Extended, Journaled. If this has never been done then you need to partition and format it before you can use it properly on a Mac.

Try re-indexing Spotlight by excluding your hard drive and then remove it.

Spotlight – Re-index

Eric,

Not a Spotlight indexing problem unless I've missed something.

I highly doubt you are missing something.
