Ideally, the sleeve sits on a "shelf" of original block material near the bottom of the bore. The shelf prevents the sleeve from migrating down the cylinder wall under compression from the head and the fire-ring of the head gasket.
No shelf...I'd be VERY suspicious of that block. Sounds like it was sleeved by someone who didn't know what they were doing.
