No, it should not skip modules.
It thinks those are installed for some reason and may just be trying every plausible address for that chassis since it cannot reach the cluster.
What's odd is 03 and 17 are missing - the two I was most interested in.
Has anything else been replaced (e.g. cluster, ECU, etc) ?
Not having the original coding for 03 could be tricky but it should be able to be reverse engineered.
The cluster is what controls comms to all the module so suspect wiring can't be ruled out yet.
A more recent scan would be more helpful, when you have the time
