It's not detecting this map. It says that it is either unranked or very new which it is not. Even though it's been months since it was out already. I tried using both my own replay and a fresh new replay downloaded off of the website. Neither worked.
EDIT: Tried out a couple of other maps and it seems to me that the database has not been updated since at least the beginning of 2016. So any maps ranked after 2016 probably won't upload.
