So this is a regression.

Note: also reproduced with Polish language. I also changed system locale, but it didn’t fix the issue

@btlechowski the fix I mentioned above is just for the Japanese and Indian lists, but that’s already available everywhere (shipped as a component update).

If there are still other locales that should be pre-selecting lists and aren’t, let me know and I can push out a similar update for those as well.

After changing language to CZE, Easylist-Cookie List - Filter Obtrusive Cookie Notices was added to the list I would expect CZE, SVK: EasyList Czech and Slovak to be add. This could be related to https://github.com/brave/brave-browser/issues/20825
