I'm trying to stack the "up in the air" Evo and the new "the duck" Evo on Rômulo José Cardoso da Cruz, the ST, from RB Leipzig, he has Enforcer, Press Proven, First Touch, Game Changer, and Finesse S...
geesluiss You need to understand, there are 2 factors associated to evo upgrades. One is requirement limit and another one is upgrade limit. Even though your evo has playestyles requirement limit of 10, there is upgrade limit which usually max of 7 or 8 only.
You are not receiving more than 7 base playstyles because there is a limit of 7. Please refer below screenshot of The Duck evo. Hope you understand how Max Upgrade Limit works in evolutions.
Also, do not always rely on external sites like FUTBIN. I have seen FUTBIN also makes mistakes while calculating order of playstyles applicable during evo chain.
