Right zone media suddenly stopped working

When I go to my favourites in the right zone media, i’ll click a folder and it will be blank , no samples no files, folders etc nothing. If I click the show all item in the top corner it will show my favourite folder and work as normal.

Any one got any ideas on what’s happening. I’ve trash preference deleted cubase ,re-installed and rescanned media bay multiple times. I still get the same result. If I fire up Ableton that works fine so don’t think its the hard drive (It’s an external)

This has happened overnight, it’s been working fine for the last 3 weeks.
