F7 pro orange thing on back

Yeah this is a bug that appears in game it also effects the team name on the front of the helmet when equipped. Would be great to post a screen shot. I doubt it would get fix because the season is almost over. You can try equipping a different face mask. I notice this also happens with different addidas cleats in game. It's like it's trying to render the design and constantly flashes. I'm on Xbox and this does happen.
