Neatline Exhibit Waypoints Missing

After updating Neatline to the 2.6.3 version I noticed that my Neatline Exhibit was not working. When I went into check it, everything was gone. None of the Waypoints were mapped. It was if I was starting from scratch. When I changed back to the previous version, it was still like this. Any ideas on how this happened and I can prevent it from happening again? I am working on trying to restore a back up and if that does not work I can take the time to recreate it. I am just concerned because I do not know how or why it happened. Thank you in advance!
