Roster thinks i have a duplicate

Having issues adding my TO ZC card to roster. It thinks its a duplicate and says i cant add him because i already have in on the roster? Yet i have Travis Hunter and Carmichael on both sides of the the ball. Though Hunter isn’t in my starting lineup his WR card from BO promo ( haven’t upgraded to the new LTD). TO’s, WR is a ghost card, where as is CB card is from the ZC side. 

Is there a limitation as to how many players can play both sides of the ball? I even tried a new lineup and added them (TO, and Carmicheal ) first and then ran into the same issue putting Hunter into KR, PR specialist??

Error message reads “Your lineup already includes T.Owens. You cant add another copy of the exact same player item to you lineup?” 

So it the ZC TO card the same card as the Ghost TO card just badged different, Because the only one I haven’t got the message was with Carmicheal cards first which is 2 different position cards but for the same promo.
