Genre pages sort absolutely without taking user preferences into account.

Environment
User is logged in and has the "Filter Chapter Languages" set to anything other than 'All' or 'None'.

Steps to reproduce
1. Go to a genre page (eg. https://mangadex.org/genre/41 for Isekai)
2. Using the 'Sort by' dropdown, select "Last Updated"
3. Observe Title order

Expected Result
Titles sorted by last updated according to "Filter Chaper Languages".

Actual Result
Titles sorted by last updated across all languages.

Severity
Low. I know that this issue is annoying to fix and might not scale well but I thought I might as well report it.

@zamu This is already known. And is planned to be fixed.
See: https://mangadex.org/thread/148705 (Chapter listing section)

That's just your personal preference

> Actual Result
> Titles sorted by last updated across all languages.

This one makes much more sence IMO. If something was not translated to your language yet - you will miss it in case of "expected result".

Edit:
Let's virtually do your "Steps to reproduce". Let's imagine there's 10 new non-translated series.
In case of "expected result" you will miss it and probably won't notice these series for months (when you already forgot about that minute interest and ignore these series in the flow of new releases).
In case of "actual result" you have the option to go to raw site and check raws for art and story (to some extent) then you can add these series to follows and read it as soon as it get translated.
