Thank you for this!
I’m actually spending a LOT of time in Sysadmin in 13 (As you would have noticed by the massive numbers of new packages appearing and bugs being fixed), so I’ll add this to my list to investigate, hopefully today!
Feel free to open a bug about this on issues.freepbx.org if you want, and I’ll update it there, or, if I remember, I’ll reply here when I figure out what the problem is!
