Hi Kristine. I am not confused at all - merely reporting a feature that is not working correctly! Here is an update a few hours ago from our "QuickBooks Certified ProAdvisor / Elite" bookkeeper:

"I have been on the phone with QB support. An investigation was opened this morning.  They have received reports identical to our issue--most invoices are fine, some are missing names.  We tried a few possible fixes, but nothing has worked yet.  They believe that it is due to an update, which I would believe to be the case as it appears that several updates have erratically "broken" something seemingly unrelated.  We have been added to the investigation."

Let's hope they can fix it soon.
