Dynasty mode vs. Play now game mode

How do I transfer my dynasty team, the team that I’ve personalized by changing players weight and height. I’ve given each player their own helmet, face mask, visor, shoes, gloves, etc….so I want to transfer my dynasty team to play a single game in play now game mode.  My team that I built in team builder, after I import it, it does show up in play now game mode, but the team goes back to generic. ???  Am I missing something?
