Font extensions + Problems in Language Fonts

I made this extension that adds fonts to simulate the languages ​​spoken in Banestorm and this extension that changes all fonts to the New Aster font, the second extension works perfectly, however the first one I'm having a problem with fonts not shown in the chat or problems with showing them in the chat, when selected, so I would like someone outside I could take a look and see if something is wrong, it is worth remembering that they are for GURPS, however at FGC it works perfectly, and the problems mentioned happen only at FGU.
