I checked the logs and you were rank 15 in your League. The relegation zone is rank 24.
If you are actively trying to drop out of Diamond, could you please get a screenshot at the end of the week of your rank and share it with us if you don’t end up where you expected again?
It will help us determine if the League board isn’t being displayed correctly again.
On the server side your score and rank are correct, so this could indicate a display issue.
