Character bug impossible to level up

[equinelizard]

Hi my account name is equinelizard, my character name is Terentian Denthur, i'm actually level 8, ready to level up on level 9.
My plan was on level 9 to take some levels on blackguard prestige class, i need all requirement ( being evil, having BAB +6, having 5 hide, having feat power attack and having feat cleave) i try to level up, but it doesn't allow me to take the PRC because it says i don't meet requirements, i asked a DM in game to help me and he told (DM Fernir) that my character doesn't shows the Cleave and power Attack feats, even if i am actually using them during gameplay (and they appear on my character sheet).
It suggests me to post here to solve this bug.
Note that, i have enough experience to take level 9 but i didn't take it waiting for this bug to be solved.
thank you for your assistance

Do you have a applicable god for the class?

There's certain classes of feats that DMs can't see on your character sheet in-game due to various DM Client shortcomings. I'll take a look at your character offline.

Please post or PM your Bioware username and original character name.

Now that i think about it. Do you have a Dexterity modifier? (12+ Dex) - if so, it might be because you don't have five ranks in hide, but maybe four, and your Dexterity then adds the last.
