Discourse incorrectly marked original posting as not being english

For some reason, Discourse decided this English posting was in Japanese:
Help : Can date parser be disabled for fiction writers?

How can I reset the original posting to be recognized as English and delete the English translation page?

I’ve reset the language of the post and topic title to English.

Thanks very much. I fumbled around but didn’t find any promising options.

Maybe language overrides are Admin trust-level features, not Moderator

I clicked on the language icon at the bottom of the post, and selected the “View 1 translated locale” option. You should see the following dialog:

The “Topic title language” will only be displayed for the first post in a topic.
