Felt like I won the lotto then got put in my place

Found the Steelers 75th alternate jerseys on the AH for 550 coins.  I was pumped to finally find alternates on the AH.  they say that they are away jerseys when I put them in my lineup.   Load into first game and they are black jerseys which is fine with me.   Now every time I play they just show up as the regular Steelers away jerseys 🤷‍♂️
