ME 2 new playthrough Sniper Rifle ammo bug!! Help?

Played ME2 many times, lots of second-playthroughs.  No big problems before, except now. This time, my Mantis will not equip more than 9 rounds. As in, 9 shots. Total. Can't pick up any more, and Reload button doesn't do a thing.  Never done this before on my second-playthroughs, so I think I can safely say it's not just because I'm a vanguard and not normally skilled at sniper rifles until the derelict reaper trap.  How do I fix this, though? It's a pain in the a-word, makes fighting a bit tougher. The pistols and smg's suck damage-wise in this game and always as a vanguard biotic charge is never close enough to hit the target, so sniper rifle just seems the appropriate choice (especially with sneak attacks).

So how the heck do I fix this bug?????
