Games won't synch.

I need help on saga... We have PCs and tablets all with Candy crush saga on them. Something happened recently... on one of the android tablets, the game is at 10351 and has the correct avatar-( two people) Other tablets and PCs are at level 10311. No mater what I do, I can't resynch those up to 10351... Iv'e tried uninstalling, re install, link in with the correct facebook account but they refuse to do anything other than lock onto level 10311. Can anyone help with this ? I'll add, on those tablets, I can scroll to 10351 and play the game, even though my avatar is not there. Normally, you cannot play any further forward than the level you are on ( i.e. My avatar is on 10311 yet I can play 10351, and presumably all inbetween)
