Samething happened to me and my handhelditems.com screen protector. It is because the screen protector was not aligned properly or it could have been cut too big. If you look at the edge of your ipad screen where it touches the aluminum you will see that there is a thin piece of black plastic that separates and keeps the glass screen from touching the aluminum. If the screen protector is not aligned and touches the black plastic part it will not sit flush with the glass screen which will not stick down. Mine did the same thing by the home button and i just left it. Doesn't matter to me since my case covers up the edges and you can't see it when it is in the case.
