So I satisfy all the points you've stated. I have a high win rate in both leagues, my current season has a lot of wins in both leagues. The 2nd half of my season for both teams last year was a high win rate. Both leagues all have different managers. I should be seeing my rating increase at the very least proportionately to other managers.

There are multiple managers that are only playing in one league who had rating adjustments of 14, 15, and 18 this week. One of the managers who is playing in both the same leagues I am had a rating adjustment of 42 points. I have a rating adjustment of only 19. It seems to me that it is only counting the win from one league and not counting both leagues.
