Tournament score stuck at 856

After playing around 15 games it became stuck at 856 win lose or draw in the tournament, my rank is going down as players are going above me but mine doesnt change. Any ideas on how to fix this?

With this tournament your highest score counts for leaderboard and is displayed to you.

Trust me. Way better than dropping trophies but on a side note wait till #1-#5 becomes “battle it out to hell” mode

Thanks you comment
