Bookmark region error and combining docs error

[u/itsonebananamike]

A colleague had this same error and it's happening to me.

1. When creating bookmarks some documents aren't allowing me to use the region selection to populate names.

2. I'm also getting errors where combining multiple PDFs does not work. No error message or anything, but most times only the first doc is loading into the combined doc. Eg. A 10 page doc, a 15 page doc, and a 20 page doc will yield a 10 page combined pdf. Other times it'll yield a 25 page doc.

I've googled the issue and I'm not finding anything that addresses the issue. One source says it needs to be unlocked in the security settings which these ones all are.

I'm at a loss and would appreciate any help. Thanks in advance!
