Unable to leave a shared file from my adobe creative cloud shared area

[Pascale5D6C]

I keep accidentally opening an outdated file that was created by an ex-colleague who no longer works here. 

In the Creative Cloud shared area, I click on the checkbox on the document and there are no associated actions available.  It's weird because I have other outdated files (shared by ex-colleagues) and I'm able to leave those easily. Just not this one specific file.  It's driving me insane.  Please help!

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Creative Cloud forum so that proper help can be offered.
