TT Hinting preview and global deltas problem

I try to add a Delta for TTFZones, but the Regular weight is missing (see image).

Secondly, the red outline is supposed to be the hinted shape, right? But the pixel don’t follow the red line (also see image).

I’m using Glyphs 3 (3083).

The deltas are attached to the instances and not the masters.

Yes, I know, and I also have an Regular instance. But the deltas are handled in the Masters tap, right? All instances show up, only not the Regular.

btw, when I use Diagonal (D), the red line disappears. Not sure if this is intended.

The code for the diagonal instruction is probably broken. I would advise to not use it any more.
