When selecting a typeset of an added font. Selection is not executed or saved.

I formerly used Windows 10 and paintdotnet. After switching to Bazzite Linux I found lazpaint to be similar and convenient.
I have a project I have been working on for almost a decade. I just realized I will need to have the font Bahnschrift Condensed or rewrite thousands of lines of text. I added to the font to my system, and confirmed that the typesets looked correct in "system settings > font management."
When using the "Text" tool, all typesets in families switch perfectly, except those in the added Bahnshrift. All Bahnshrift typesets, when selected, look like Regular, and regular is selected when I click "choose font" again.
I have tried reinstalling the fonts, and lazpaint, to no avail.
