Solo Battles Glitch (Not allowed to play last game) 3+ weeks issue.

I've had the same issue for weeks now, where the 13th game (and many times the 12th game) aren't available to me to play. The game considers them played, even though I've never touched them. It's also prevented me from hitting the reward level that I should have been able to easily obtain, had those final 1 or 2 games been playable.
