Oops, you're right: this is a small bug in the GUI. It will be fixed in
the next release.

This is normal: a transfinite volume can only have 6 or 8 faces (for
which we can do a transfinite interpolation--see tutorial/t6.geo).
You'll have to divide your volume into subvolumes (or generate an
extruded mesh) if not. Gmsh's structured mesh algorithms are *really*
primitive...
