Old ticket numbers upon new ticket creation

Old ticket numbers upon new ticket creation

I am having a problem where a user sends in an email to create a new ticket they get back two emails. One email refers to an old ticket that the user had nothing to do with. The other ticket has the correct new ticket number on it.
 
This doesn't seem to happen for every user every time, just randomly. This just started, we were running 9.0.46, I upgraded us to 9.1.10 and we are still seeing the issue.
