Change language in labels

Hi!

I use Wix-hotels and have choose the language Swedish (svenska).
So far so god. My problem are when I implement Wix-hotel to my site, the labels are in English.
How do I get the labels “check out, check in, search, read more” and the rest of the original text in to Swedish ?

heres the site https://test.sundsvallsbhk.se/boka#/rooms

Thanks !
