Effra Font Won't Display Correctly

Hi, I have read through many posts and have worked through how to add web fonts and map fonts. The process has worked for other fonts, but I cannot seem to get it to work for Effra.

I am on Axure 9 on Windows. I have an Adobe Creative Cloud license and have activated the Effra font family. I have tried everything and I just cannot get them to look correct even while I am working in Axure, let alone the preview. Any ideas of other processes to try?
