Why can't I add any Touch Bar buttons?

I just installed BTT on my MBP, Mojave and am unable to get started with it!
I've enabled BTT in the Accessibility | Privacy settings.
I tried restarting multiple times.
The best I can do is make the BTT icon show up in the Control Strip:


but the icon doesn't do anything.
I am unable to add any buttons (+ TouchBar Button) in the configuration dialog - in fact the "1" and "2" guiders never even go away!

No luck with the new UI either. Am I missing something really obvious here?
Thanks for any tips.

For some reason no master preset seems to be selected.
Could you click on Manage Presets, then select the default preset in the master dropdown?

I think I know what caused this and will upload a fixed version in a minute.

That worked, thanks!
There was no default preset btw, I had to create a new one.

Yep, glad you reported this :slight_smile:
(the default preset was only generated when using the old UI).

Is there anything special about the default preset or is there a way I can recreate one?

Nothing special about it!
