Does the "G" character show up on groups for you? The code agrees that it should be there, and I remember formspec render sorting was changed at some point around 0.4.14-0.4.15...

Note that item image buttons allow to have their own label. I recommend to use that one. Unless you can think of a better / more obvious to display this (maybe different background color or whatever).

Did you maybe try to overlay a label over an item image button?

I have overrides for groups now, but they're currently only applied to group:wood and group:stone.
Suggestions for more would be appreciated if you find any.
