Offset Curve filter custom parameter height/width do not edit correctly

Hello!

In Glyphs 4107, I am not able to set a Offset curve filter custom parameter and edit the vertical and horizontal offset values.

No matter what I do, one or both of the values end up getting reset to 0. I have enclosed a screencast showing the unexpected behavior…the expected behavior here is for the text to read 5;5;0;0.

This is not an issue if I go to Filter > Offset Curve and copy the custom param from there.

I hope this is helpful and that it’s not just me doing something silly. In case it makes a difference, this machine is running an old version of MacOS (13.3.1), so if you can’t duplicate, that’s probably it. Thank you for all your work on Glyphs 4!
