Changing Ownership breaks and/or resolves my notifications

My coworker set up several notifications. When he left, I updated his user/admin permissions. The notifications stopped working. I switched the "owner" on one of them from him to me and it started working again. So, then, I switched owner on all of them. The others stopped working but the one I changed still works. Is there a known issue with this? Should I delete and rebuild the notifications? Any suggestions?
