Don't sweat it. It's sealed and should be ok.
The thing about wax though is that a cheese can still get mold underneath. So don't get disappointed if you do have molds on the cheese after aging even if waxed, it'll still be good. You just need to scrub it off.
Also, molds only grow on the surface. So as long as there are no cracks on the surface of the cheese, the interior will be just fine.
