[Client] Highest rank wrong.

[Client] My highest rank is incorrect as it says P1 when the highest i've ever been is P4 (Current Rank).

I have seen another post that was simmilar so this is not an isolated incident, and i have no clue how to recreate it.

It could be displaying highest mmr, or highest calculated positional ranking as an idea? The other person was gold 5 had it showed gold 1 as highest. This is not a seasonal best, it is an account best.

Update: I now have lost my plat border and have a silver one, my past rank says Silver 2 now.
