Kingdom Hearts 358-2 Days Levelling problem

Hi guys, i've just started playing KH recently and currently in Day 14.I couldn't level up my roxas even thou he has 4k+ exp. Didn't get the level up panel.
Can anyone help me or know how to solve this problem?Thanks in advance :)

So you didn't get the level up panel ?
That's odd....Have you fully fill the experience gauge after finishing a mission ?
That's how you get a level up panel

On my Ak2i (when it was alive) i'l had almost aload of bugs , it's the game , like when i saved a time my play time was 999:99:99 óó . It's just the game , they dumped the game with a load of bugs .

go re-download the game... i never find any bugs when i play KH...

Me neither, never had bugs. what you could do is try to get cheats maybe? Just to see if you can actually get the level up panel on your 'Bugged Version' of the game

did you use cheats? i don't get how you get 4000 xp and not level
