Why is it claimed that there were 7 players? When the present was 8. Because of this, the game did not affect the rating. Maybe bug?

Recently looked at the repository. Found that my map is hidden. After reading the new rules, I understood the reason. Map name is incorrect. (Map name: "SunnyArc_v1")
What can I do to make my map unhide?
Is it possible to rename a map? or need to upload a new version?
