With the new UI, the localization of "World" for the favorite lists and "Groups" for the list is broken on the profile.

In the first screen, i'm on my main account, you can see both are in English as I have worlds in favorite lists and i'm part of groups.

In the second, i'm on a second account but both are now localized as I do not have any favorite world, nor am I in any group.

Third screen, I join the Crowdin Translator group and the text "Groups" switch back to English.
