Without seeing the bow it's hard to tell what's going on, but..........did you get the bow at a Martin dealer? If so then were you aware of the problem when test shooting it? If so you shouldn't have bought that bow. That's why we always recommend shooting the bow you intend to buy.
Maybe I'm picky, but a good shop would have you try the bow and watch for such things while you were shooting. In that case he would not have sold you the bow; at least without checking it out.
So what are your options now? Depends on the dealer. If it were me I'd take the bow back and give you another. Then get that one fixed by Martin, but that's between you and him. The very least he should do is take a look to confirm what you have said and do whatever is necessary to make you a happy customer.
No doubt Martin will take care of things, but they will want you to make every effort to work trhough the dealer--first.
