It appears to be functioning correctly now. I can't explain why. The only thing that was done differently is that TT was disabled for a day and then enabled just tonight. Before this, we were getting 2 alerts for EVERY quote. Was driving us all buggy.
If you encountered again, please try to comment the function of alertQuotedMembers in libarary/Tapatalk/Model/Post.(php code). Do you know how to comment php code?
