Anyone ever have this happen?

I'm grinding gold SP quest today, and while im doing it I figured I would level up all the R hime I have to 30. So I doing this and swapping himes out as they get to 30. Last battle I leveled up, had one hime hit 30 went to change her out and its as if the battle never recorded, shes at 27 and some of the level 1's from the last swap are still 1. Just curious if this happens often or what? I've relogged, signed in and out etc, no change.

Thanks
