Kongregate API Only updates Highscores Once

So I have Kong API working with my Unity3D game but I think there must be an issue somewhere. If I lose a game I send the stats and it goes into the high scores no worries but if after that I start a new game by using Application.loadlevel to reset everything the next time I lose it doesn't update the scores. Instead it does nothing. I know its still connected because it says my username name the entire time.

What could cause this? Is it an issue with my game or is it a Kongregate thing?

Cheers.
