LiteSpeed Cache and Translation

I’m facing issues when enabling the server side cache (LiteSpeed) on my WordPress installation. I’ve enabled the automatic translation on my side to match the visitors OS language. This works great, until I enable the LiteSpeed cache plugin (default configuration). Then, all users see my OS language instead of their own. Do you have any hint on how to solve that? There are tons of settings in light speed. How does the automatic translation work? Is it some javascript running when opening the side. Any hint is appreciated.

Thanks, Pascal
