Prop builder betting limit per player

So i like to do lotto type parlays. If i do a prop parlay with say 10 legs and it totals 10k. I can no longer use any of those players that reached a 10k payout. So basically im limited to one parlay. I cant use those players in any other parlay. It will say selection exceeded.

I asked to have the limit raise but they said it is handled by a 3rd party. Does anyone else have this same issue?

Seems like nba is 10k on prop per player max

Nfl is 20k

However sometimes its less. I can do lets say a 2k parlay and then it will only let me add 3k more.
