So I downloaded the japanese language package so I can play the game with Japanese audio but with english subs and interface but every time I exit the game and relaunch it my language settings keep going back to japanese everything and so I have to change it back again. Dunno if this is by design and I get that yes I download the japanese package therefore the game will auto launch in japanese everytime but think we should be able to keep our settings.

I bought the game via steam and in steam i was able to change the language with right click on the game in the games list and then properties, language. Selecrt it and there you go. Sadly i dunno if gog provides similiar functionalities but give it a try.
