Messages not showing up in Mailbox, but are there in Find/Search

I have a user who has an empty hole in her GroupWise Mailbox from 6/29-9/19. The messages being displayed are missing all email between those two dates. However if you search for a message from that time, they all show up in the Find window. I have moved them to a folder (where they do appear) and then back to Mailbox but still nothing.

I have reset the Mailbox view to Default to no avail. I cannot see any filters in place, etc. Just very odd behavior I have yet to see in my 15 years working with GroupWise.
