Fut birthday evo not working

I spent hours grinding to get 325k for the store pack to get the building your own fut birthday evolution, and I put it on my 92 rated striker which met the requirements just for it to glitch and not remove the playstyles for me to add the new ones that I wanted it just added the fut birthday card design. I’m extremely frustrated because I genuinely got excited for the evo just for it not to work.
