Sorry if I'm a bit late, just found this asset and had just found out how to change the language but to change it, go into the main resource > script > configuration > client.config.lua and where it says "m_languageCode = "de", change "de" to "en". That should fully translate everything from Deutsch to English!
Again, sorry if I'm a bit late. Hopefully this will be useful for people downloading this asset in the future!
