I think they're asking about when the list resets and the rewards are updated, not the max you can build up.
Regarding the available leves resetting, i dont believe they do. Came back many days later only to find the same rewards still up.
Opposed to 1.0 however, they no longer run out. They get refreshed instantly after completing it, with new rewards. So the only way to get the leve list to "reset" is to simply clear all 3-4 of them as far as i'm aware.
