Added fonts continuously being unusable across the Creative Cloud

Hello,

Wondering if anybody has had the same issue and would know any fixes?

The issue is:

The majority, if not all, of the fonts that I have added to my Adobe Creative Cloud, whether they have been download from Google Fonts, DaFont, etc., continously stop working when I try to use them across the Creative Cloud softwares. They still show us 'Installed' and 'Activated' but they do not work. 

I have to keep closing down the software, deactivating and removing the fonts, restarting the Creative Cloud and then adding them back to be able to use them.

Any help would be appreciated.

George
