The actual list of Networks just shows list of different subnets without any context, ie there is no location shown so you are just shown a list of meaningless networks. I try added description to each Network, but this does not help when you come to select a Parent network, as the actual Location is not shown, just other subnets without any reference to what they belong to ie you get: 10.1.0.0/24 or 10.1.0.0/24.
