Query: Two different sizes?

I just received the gloves and the left hand is one full size smaller (and believe me, my hands are the same size... I don't have the problem of having one hand being bigger than the other). Both gloves have a tag inside that say they are both M size, but the left is uncomfortably smaller. My best theory is that the warehouse some how accidentally attached a M-size-label to the left hand glove. Now what am I supposed to do with half a pair of gloves?
