Can't delete files in Bridge 2018

I recently got a new mac, well new to me, and signed into my CC account to work on some images.  I can't delete any files from bridge.  I could on my old computer.  when the dialogue box pops up asking if i want to delete or reject, i click 'don't show again' and hit delete.  nothing happens.  i can't use command and delete or the trash can icon either.  I'm at a loss.  And I can't find a way to actually call and speak to someone.  Please help!!!!
