Connectivity Creator - after cut of nodes only from one hemisphere, the split by left/right is incorrect

Large Scale Connectivity Viewer launched with the default Conn 76.
Launch creator for another Connectivity after cutting out 3 regions only from the left hemisphere and give name "cut-3-conn"
Load in Large Scale Connectivity Viewer "cut-3-conn"
Observe the split by hemisphere on this new connectivity in the quadrant viewer (for weights or tracts). It should be asymmetrical (35 regions in the left hem, and 38 on the right one).
Instead the current viewer it splits in quadrants simply by dividing the regions in 2.

Pls investigate first what is happening in the code, and then think of a solution
