Hi Rafal,
Based on the transport file, problematic device was discovered under 5 different IP addresses, but full Inventory data are available for 3 of them. SNTC logic removed duplicates and narrowed down 3 to 1 (.240), but remaining 2 (.247 and .248) were processed partially.
You can try to fix this by removing duplicates on CSPC side (Settings > Discovery Settings > Serial Number Duplicate Check - YES).
Alternatively, you can blacklist unwanted IPs under Settings > Do Not Manage Devices List.
Best Regards,
Greg
