Hi Febelus,
I tested in my lab this morning with IMC 7.3 E0506P09 and the latest IMC 7.3 E0605H05.
I see the same behavior you are reporting with the missing sub-view folder whenever I add a GIS map, so this does appear to be a possible bug.
Regarding Live Update in IMC not finding the newer software versions, there was a certificate change on the HPE Software Depot that caused IMC to not be able to access. IMC 7.3 E0605H05 contains the new certificate and should restore Live Update function.
For the Network Topology with GIS mapping issue, I would recommend logging a support case.
