Network scan issue

Network scan issue

I am using SDP on demand/Assets:

I have setup a probe but network scan does not bring up all the printers found.

Checking the logs on the probe install, can see it has discovered all the printer ip, and the network scan result also show the printers was success, five in total. However, cannot locate any of them except one.
and there are no unknown OID to fix.
All the printer are of the same make, and I have a feeling that this is the issue

Anyone come across this issue, and way to fix it?
