TTF zones 🡲 (Δ) 🡲 Cannot click on field to step through the available options


I am using Glyphs 3.0.3. I am wanting to shift TTF Zones one pixel at certain px sizes using the (Δ) dialog. However, I am not able to click on any of the fields. I am in the main master when doing this.

The (Δ) dialog is working for TTF Stems.


Can you please send me the .glyphs file to support (at) (this website without ‘www’ or ‘forum’). I will have a look.
