Hi Catherine
this is an artifact of visualizing a slice through a 3D surface. There
are no true bubbles allowed - it is definitely all one surface. When you
see something that looks like a bubble, view it in another plane. I also
wouldn't worry about small oddities in the inflated surface - it's mostly
for visualization.
cheers
