Hi, so I'm trying to add multiple languages to my skill mod but I guess my string tables are connected so I guess I'm wondering if it's possible to make more than one language or how I can force the game not to translate into the language and keep beeing English?
And it keeps saying Program instead of my skill name ingame
(I searched for a simular thread but didn't find anything)

String tables share an Instance ID that must be identical in all but the first two digits, which act as a bit identifier for the language. For example, the Instance ID starting with 00 is English.

Sims 4 Studio can auto-generate the other tables for you, from Tools > Modding > Copy string tables to all languages.
This will populate every language with the English set, until they're edited to add translations.
