Disk Utility Error

When I run the disk utility displays the following errors that it does not fix, yet it says Operation Successful at the end.

Also Boot Camp cannot partition the drive for a Windows install -which is why I ran the disk utility to begin with. It indicates there is corruption on the drive.

I booted in the recovery mode and ran the disk utility but it still would not repair it. I re-installed the OS from the recovery mode (without a reformat of the internal drive) but that did not resolve it either. Otherwise, I'm not having a problem running my system and it has been backing up to Time Machine successfully.

Anyone have any ideas? I'm running Mac OS 10.14.3 on a fusion drive (late 2013). It converted to AFPS within the last several months (when it came out for fusion drives). Here's the log of the Disk First Aid. It shows the same errors when I run it in recovery mode.
