Myfonts does not recognize font styles

When I upload my variable font on myfonts, the “default display style” doenst properly recognize, that there exist several styles. It only suggests the “regular” and this regular isn’t even the regular style in my font but the Condensed Regular style.
Any idea where I got something wrong in my glyphs file?

You will need to post more details of your font metadata. Can you show your instance definitions in Glyphs, as well as your variable font setting?

The Condensed is the one displayed at the moment.
Thanks in advance @SCarewe
