Font Ordering appears different on Creative Market

Howzit Guys,
I’m currently uploading a typeface on Creative Market and have just realised my font weight ordering is appearing differently on the sites preview. The typeface has 5 weights (normal (400), regular(400), medium (500), semi-bold(600) and bold (700) (see attached screenshot). All the weights are appearing as 400 on CM which is mixing up the order (see attached screenshot).

Please assist, thanks in advance.

Regards, Fhumulani. (Glyphs 2.6.6)

Can you check if the weight class is correctly set in the fonts?
