CouchSurfer - can't delete blank bookmark

Hi, I’ve got a blank entry in my bookmark list that doesn’t go when I try to remove it - any ideas? Think it was created when I tried to bookmark a page CSP didn’t like even although it’s fine in all other browsers I’ve tried on my PC

BTW, tried looking for the bookmark file as identified in older posts with no luck either

I have the same issue.  I have 2 blank ones that i can’t remove.
