AST2 OS Diagnostics Getting Greyed Out

Hi.

After running a test in AST2 (doesn’t matter which one (EFI) or (OS)) the tests that require an OS get greyed out like in this screenshot and I can’t select them. If I archive the session and start another one in GSX, they become available. However, same issue occurs after I run a test again so the issue repeats itself. (And I can't keep doing it like this because it takes a lot of time to restart the computer every time) This was not a problem that I had before. Has anyone had an issue like this? Is there something that I am missing or doing wrong?
