I have a user that attempted to enter a call back phone number into the Details portion of an issue being created and I watched live as the number disappeared. He tried several ways of doing it, 123-456-7890 and it disappears, (123)456-7890 and it disappears and any other variant all disappear. The only one that works is 1234567890, this is very odd, I cannot find a filter setting that would do this either. Has anyone experienced this?
