First Aid Failure

I recently updated my iMac for a Safari security update. It finished updating, and gave me a white screen with apple logo. I force restarted it and when I turned it on it booted up successfully to macOS 10.13.6.

When it booted up it was acting pretty weird, being extremely unresponsive, beachball of death a lot, so I checked Disk Utility and it was fine. I then booted up on another partition with El Capitan installed and I reset my PVRAM, used Disk Utility in Recovery Mode and nothing changed. Then I used Disk Utility from El Capitan on my High Sierra partition and it says that it was unable to complete First Aid. Does anyone know why this would happen?

I attached a screenshot of what Disk Utility says right here:

iMac, OS X 10.11

First, you are using an older version of Disk Utility in El Capitan on a volume containing High Sierra. You should use the Disk Utility installed in High Sierra. Do this by booting from the High Sierra Recovery HD - Restart the computer and, immediately before or at the chime, press and hold down Command-R until you see the Apple logo and progress bar. This should take you to the Utility Menu from which you can run Disk Utility and run First Aid.

Thanks, this is something I probably should've thought of.

But when I tried this it says it’s fixed it but the OS is still quite buggy, so I’ve just decided to do a clean install of High Sierra.
