Font Output By Glyphs 3 is Positioned "Higher"?

Hi, I’m experiencing a strange issue where the same font exported from Glyphs appears to be positioned ‘higher’ compared to the one from FontForge. As you can see in the picture, one is from FontForge and the other from Glyphs 3. I’ve tried adjusting their metrics and tables to match exactly, but the problem persists.

You can compare the output files with FontTableViewer.

And check the vertical Metrics tutorial: Vertical metrics | Glyphs
