Save option glitching on my game

My game has been glitching for a few hours now.....I played my 2 matches for the day, tried to change players round and every time I try to save my squad change its says I have lost connection. No connection issues though as reconnects me and can do other things in the game like buy players. Please can you look in to this as I need to change my players. I sold my right back and a striker has automatically replaced him! Also at one point during my trying I had 12 players in my first team, 2 Left midfielders were showing but not when I went into formations. Very strange. Oh and Keep up the great work. Love TOP ELEVEN! My Team is LEEDS FC, thank you.

I play on iPhone 4 if that helps resolve the issue in anyway?
