There are a few things going on here, so let’s break it down.
First off, the daily game cap has been removed. The screenshot you shared is not a bug, but in fact a feature. If you want to play 6 players at G today, you are more than welcome to. You could have played 9 yesterday. Since you played 3 and they all played, you have 6 remaining. This is true for the rest of your positions as well.
The other issue you raised is a good one and related to this:
Projected games remaining should update immediately upon clicking Bench All Players, it should not take 10 minutes. I’ll look into this right now.
I am not sure what you are referring to here. Projected Games Remaining never affects benching of players. Only Games Remaining. If your projected games remaining for the whole week is at -1 but your games remaining in the current moment is at 6, the player will not be benched.
