Vertical typesetting in the Edit view

Hello, I’m using Glyphs 3.2 (3236) on MacOS 14.2.1.
I’m making a vertical font, and I set all TSB and BSB of the glyphs to 100 to make them spaced 200 units from each other.
However, when I typeset texts in the Edit view, the characters’ position gets messed up, as shown in the screenshot below.


Therefore, I wonder how I should set the metrics in order to keep every glyph spaced evenly in the vertical typesetting mode.

Thank you.

Can you send me the font for testing. I just changed a few things. I might have broke something.

This is the subset of the font I’m working on. You can test using this file.
