Rank for core tdm

I hit onxy 3 on tdm 100% but it doesnt say elgiable for promotion can someone tell why it wont update

Screenshot?

Just wait, I hit 100% 3 times last week and I played multiple games after thinking a win would update it. That was not the case, I had to battle back for any lost percentage, so instead once I hit 100% that third time, I went to bed and when I woke up it was Diamond.
