I'm trying to add options to ticket source. In research in this forum, I find little info on how to do this that isn't years old. And, I find that osTickets has two different lists for the same field. When creating a new ticket, there are only three options. However, when changing the ticket source of an existing ticket, I get five choices.

I found the five options in class.ticket.php, but I haven't found where the three choices are in the code. Also, why is the same field using two different sets of data?

The class file and the db enum match all five sources. I'm still not finding where the three sources is coming from?

osTicket v1.12.2 // osTicket-1.12.2-Awesome-101
PHP 7.2.21 // MySQL 10.2.26 // Apache web server
