Pushing all characters on line all to the left in proof

Hey! I’m new to glyphs and still sorting things out so hoping this is an easy solve. I’m working on a file that used to be a UFO, and the test exports have been going well for a couple days. However today after working on some spacing, lines in my preview have started to compress all to the left seemingly at random. I haven’t been able to figure out what causes it, each glyph typed on it’s own doesn’t seem to cause it, and the same paragraphs are working with other fonts. My only thought was that maybe something had crazy negative spacing? But none of the glyphs spacing seems to be unexpected.


How do you text the font (where is the screenshot taken)?

Sorry missed this note coming in but thanks for the reply! I reset the whole computer again and problem solved ! (of course!) But I was proofing in indesign.

Are you using the Adobe Fonts folder?
