My Facebook showing me a different team and nationality 2 wat am using in LET ME PLAY

I have been playing T11 to level 2 without connecting it with Facebook, but now I want to connect it with my Facebook account and its showing me a different team entirely thereby making me run two accounts which I don't like to do. and also showing my nationality in Facebook team as a NIGERIEN rather than NIGERIAN? I have tried removing the one on Facebook so I can use the team am used to, But anytime I want to connect with it, it keeps loading for a while and finally tells me I have a team already on Facebook, this is really killing me considering the fact that I have the like of messi and henrik Larson in this team. Thank you.
