One of the premade managers has an outfit with a tie, when you change the outfit the tie stays. And If you don't have any tie unlocked you can not get rid of it.
Ideas
This issue has been ignored for six months. Have posted a number of times in the past, only to see discussion forums closed, because development team only cares about Ultimate Team. There are more than a hundred career mode problems still in-game dating back ten years or more that are continually copied and pasted from older game versions. For the first time since FIFA 16 will not be preordering game in August. Waiting until Halloween or Thanksgiving when price drops to twenty dollars.
