Thank you for creating a new ticket. I understand what you were trying to do now, before I thought if you were asking if the bug had been fixed.
Before that message was being place on every order email and out fix was to set it just for orders with tickets in them.
There is a filter to change the message.
I created this coding here and that should get you close to what you are looking for:
https://gist.github.com/jesseeproductions/6a9e0674d0f2c28def03
Just drop that into your theme’s function.php file.
That removes the message, but you could add your own by place text between the quotes here:
$tribe_ticket = '';
Let me know if that works for you.
Thanks
