Hmmm, your match history shows 5 games played today (2/26) which matches the leagues audit info I have. You did queue dodge after your initial miniseries start today, which tossed you out of the series. You then won and started another miniseries.
For clarity's sake what I see in your match history on the client as of 3:21 PST:
LOSS (Leona) (Miniseries end because lost 2/3)
LOSS(Leona)
VICTORY (Amumu)
VICTORY(Udyr) (2nd miniseries start)
VICTORY(Leona) (1st miniseries start)
Does this data match what you're seeing?
As for your initial issue of getting the qualify pop up late, end of game messages may be a little delayed coming into the client during peak hours. This doesn't mean that the game results are dropped, they're just processed by the system a few seconds later than usual. You should still get all your wins/losses etc. We're looking at hardening the nuts and bolts so these incidents occur less frequently.
