Forum:Zombie Island PS3 glitch!

I have this horrible glitch in the Zombie Island DLC. First, I started the game with all bounty board quests already in my ECHO. But the problem is that there are 5 duplicates of each mission. And when i do one of the missions, when I go to the bounty board to hand it in, all my progress for the mission is gone and I can't turn it in, even though one of the 5 duplicates is in green text. This is driving me crazy.

I also have another weird but not as serious glitch in the normal game. I'm on playthough 2.5 and for some reason the game says I have to hand in a quest by talking to Tannis at her holding cell in the Crimson Prominitory. This doesnt make sense because I already beat the game, and besides, she isnt in the cell anyway. Also, when I host an online game, it says my current story quest in "Find Steele".

What on Earth is going on?!?! or should i say what on Pandora is going on!?
