When I click on a document within a group I co-own I receive "This item might not exist or is no longer available" message.  It doesn't matter if I own the file or one of our members own it, see image below.  It doesn't happen on all files and the group is setup so that all members can edit.

When I go to try and share the folder Live briefly displays "The folder is not shared" message but then tells me that members can edit, see image below.

I've tried to re-upload with no success.  Can someone please look into?
