It does'nt register that i bought even more that 3... And if i sell some cards the number goes back
Oh, that's because you bought packs that weren't "Bronze I", you have to specifically buy "Bronze I". You bought a Bronze II pack or something because you have cards with power of 4 on it. My suggestion is to redo the intro and only buy the first pack 3x. Also to note, don't sell any cards until you've done the objective. It probably messed up the calculations the game is doing.
It seems like you're trying to load an old save file on a newer version, I can tell because 0.08B is supposed to start you on $1500 but you've got $500 before you opened the deck manager. I'd recommend starting a new game to fix your problem, (you can literally just press 'skip tutorial' to get back to the same spot in 10 seconds because that's as far as that old save is).
There's also the possibility that the game didn't update properly because every time you open a pack, it SHOULD give you 5 cards each time, so a reinstall could also be needed.
