How do I switch my EA account back to Xbox 360 after login from Xbox One?

 I have Madden 16 for both consoles and want to continue playing the Xbox 360 version where I have built lots of coins and players in Ultimate Team. My EA account now shows me as an Xbox One user, but I want to continue playing Madden 16 as a Xbox 360 user. I am still playing Madden Ultimate Team on the 360 but my EA account doesn't show my players. 

How can I switch back to 360?
