Achievements not unlocking, multiple

[jpm5150]

Hi,
So, I started playing the game, got 5 achievements for the first level, elemental gate, etc...now achievements have stopped unlocking for no apparent reason.
Ones not unlocking:
- Equip a hat (I have two hats, have tried both on different characters
- Complete a challenge...I successfully finished one, no cheevo.

Thoughts??
