Vertical width is not interpolated in Variable Fonts

Dec-31-2022 16-10-22

Hi. I want to make the same font as the reference above. I’m trying to create a condensed typeface for vertical writing. I created two masters and assigned vertical widths, but they only move in place. Vertical width and vertical side-bearings remain unchanged. I’d like to know if the glyphs(Ver.3.1.1) don’t support it or if there is something I missed.
