Sounds like a bad batch of blades. It would only take a few degrees to be off on the cutting edge and it won't cut worth a dam. You can either buy new blades or try sharpening yours from the bad side. By sharpening yours from the back side, you should be able to change the angle a bit and that may help. Even if it does not work, you are still not out anything. It really sounds like it is just shaving a very thin bit of ice instead of cutting the ice.
