Under Actions, Update Application Subtitle. is missing, i had three actions which are now undefined and i can only delete but i cant add them back or even editing them.
Subtitle was part of a module like extra ticket options like reopen in V4.
Can’t remember if it was changed in v5 or not but it was never installed by default on V4 so a new terminal etc would have the undefined actions.
Make sure More Ticket Options module is installed
Thank you @Jesse … My head i never thought of that next to More Ticket Actions, there is Shell Subtitle.
