Your issue is hard to follow. It seems like you bought green points with real money, you use some of those to advance faster on pro-pass thinking you were getting level of skill points faster by leveling past 50 in those. But leveling on pro-pass has nothing to do with leveling on skill points, except of sometimes giving you more XP pts to help you leveling up in skill points faster.
I do think EA should have explained this pro-pass thing better, I was confused too the first time it was introduced. Maybe it's something they are doing in some of their other games, I know 2K is doing it too with their Clubhouse pass or whatever it is called for their golf game.
Anyway... don't use real money, it's not worth it unless you really want something special. I got some 1500 green points for buying the deluxe version before the game was released. I still have them, I didn't find nothing worth using them. I'll probably be stuck with them forever.
