Same problem with me. My star Aerial Defender DC Herrera has a yellow card since more than 20 matches and it is not going t all. It was in a league and he has played 20+ matches since he got it. Not only him, i have 5-6 more players who have the card stuck to them since 10+ matches. They r supposed to go after 1 match of receiving it as far as my football knowledge tells me....
