i have the exact same issue.
My team colours are blue, red and white, and on my Home uniforms my accessories are Orange.
I cant find a way to change it either.
Please let us know what the support will tell you.
I am not asking them because every time i ask them about anything they just asking me to do a diagnostic check of my wifi, router, windows, and all the bullshits you can imagine just to create the feeling that the problem (any problem) is not from them but on customers end.
Worst support ever coming from the worst video game company ever.
