Font weight doesn't work


I have uploaded a fontfamily (Editors Note) with several different weights to my project. The problem is that the weights doesn’t show up correctly. When I select the weight thin, the Font weight remains bold. When I select extra light, the same problem occurs. All the different weights I uploaded doesn’t really variate like they should. They all show up Bold or semi Bold.

I already tried TTF, WOFF, WOFF2 formats and adding a custom code in the header…

How can I solve this, please?
