G-Drive files indicated in Quarantine Manager: What do I do?

Hi!

Have a ton of files in my Quarantine box that are indicated in my G-Drive (backup drive).

I hit the CLEANUP button and it says "Automatic cleanup was not successful, Manual cleanup is required." But how do I delete files on my G-Drive? When I click on a given file, there is no REVEAL IN FINDER button. Should I hit AUTHORIZE or CLEAR FROM LIST for each one? Or, as these are all backup files, should I just forget about it and assume I'm safe?

Thanks!
