‘Black box’ is too long. I tested several programs

I have a problem with the font,The ״black box״ is too long.I tested several programs.I made a video showing the values in the Glyphs app

The selection triangle in Adobe apps indicates the bounding box of the font. That means that somewhere in your font, there is a path that actually reaches that low. Try the mekkablue script Test > Report Highest and Lowest Glyphs to find the culprit.
