Description

Open https://try.gitea.io/milestones, click "Sort":

The tokens repo.milestones.filter_sort.closest_due_date and repo.milestones.filter_sort.furthest_due_date do not appear in options/locale/locale_en-US.ini currently, maybe they got lost somehow, I wasn't able to determine what exactly happend, but they should be re-added.

Gitea Version

Can you reproduce the bug on the Gitea demo site?
