Plugin Manager...Fix Permissions does nothing?

I rely on AF to ensure all my plugin permissions are correct, in Hi-Sierra here, ‘Fix Permissions’ is not greyed out but clicking it appears to not do anything…

Apple is locking down the OS more and more and it’s getting more difficult to keep this feature working. Check and make sure AudioFinder is given full disk access in the System Privacy settings.

Thanks, tried that but no difference…btw in Hi Sierra it’s still called ‘Accessibility’.
