I spent three hours with Quickbooks support this morning. 

Apparently, the issue is that if I have an expense that's been created through the receipts tab, you will no longer be able to add items to it. If the expenses created any other way it acts as normal and you can add items and edit as needed. However, if it is created through the receipts tab, you can edit most of the receipt just not add items.

Unfortunately for us, the items portion of expenses are very important as that is how it communicates with the other integrated software we use. This change is also retroactive, meaning any past expense is no longer editable.

Our workaround now is to create a copy of the expense we are having an issue with, delete the original, and then edit the new one it as needed. This is foolishness. I was told by a tier 3 customer service person that this is the way it's supposed to work at this point. It appears this change was made last Thursday. I hope they realize the folly of this and change it back to the way it was.
