Font family not recognized - although it's installed

[Sukma]

I have a license for Affinity Designer V1. I already installed the "Manrope" font family (it can be used in Ai), but it's only the extra light that is recognized by affinity designer. Can someone help me with this issue?

The screenshot you attached suggest that you instaled variable font.

Affinity Publisher curently doesn't support variable fonts. 

You could download static versions of Manrope from google fonts.
