i went to the pro shop today and they told me it is normal wear. first of all its the cable not the string that is wearing, i was wrong explaining it before. so the pro shop told me that the angle of the cam is making it wear but that its normal and also to keep it waxed. so i am going to keep an eye on it.

i have the 29inch module in it, its the tall brace height, 70pounds draw weight and the draw stop is on the 5th line.
