No more ‘clean library’

Running jarvis 16.1 and all of a sudden I no longer have the option to clean the library. This seems to have happened last night, since the day before i could clean it without a problem.

I know it’s probably just some setting I messed up but it’s rather annoying.

I re-installed (over the top of existing install, and nothing changed.

Is there anything else I can do or do i have to completely clean re-install
