Templates vs UCP admin

Stupid question. I have a template setup with a few basic buttons for all, then I want to customize a few buttons for each individual user, so I’ve turned on UCP admin, however when I config a BLF button in ucp admin, it is not saving the changes. it seems that the template is over-riding ucp. is this how it works? why can’t i do what i want to do here?

i found the bug here.
