If you're unfamiliar with a frame pack, the pack rides higher on your hips that you think it would. They usually aren't clenched tight on the back against the shoulders.
Finally, check that the mesh fabric crossing the side facing your back is taut. If you got it used, it tends to loosen up as the pack gets older.
