Importing from illustrator

Hello, I’m trying to important a mechano typeface I designed, into glyphs. However, it is quite a complicated design, and acting like one.

This is how it is in illustrator: http://tomjhume.com/correct

this is how it is in Glyphs: http://tomjhume.com/broken.jpg

Is anybody able to help a brother out?

have you expanded the outlines in the parts that are not supposed to be filled (the inner part of the A)?

In fonts, you can only have black filled outlines and no strokes. So you have to expand paths and assign black fill to all paths.
