I would guess that it is happening after you make a hole in your centered
clay, while you are pulling the hole out. Look at the profile of the
centered clay, you may see it is tapered down, (smaller diameter at
bottom, than at top)or slightly undercut. Then if you open it beyond the
initial diameter of the centered piece, it causes the clay to roll over
like a wave, and enclose a ring of air around the perimeter.
Try to either not open wider than the initial centered ball, or use some
downward force on the rim as you are pulling the clay out. I find this
helps keep the clay down on the bat so that it doesn't roll over an air
pocket.
If not this, then maybe you are enclosing air when you put the ball down
on the bat. Use a circular rolling motion to make a nice rounded smooth
bottom, so that this doesn't happen. A deep fingermark may trap air, when
places against the bat..
Hope this helps,
