This bug is consistently reproducible on my installation of 3.80.
I have determined that it is this template that was producing the bug. Basically, with this add-on enabled, the list of templates shown from Edit Templates is abbreviated unless I click on "Expand all". When I disable the add-on, I can see the full list again.
This is an extremely useful add-on. I hope you can find a fix for this.
