NetSUS 5.0.1 not showing latest updates

Hello, NetSUS 5.01 here does not show the most recent macOS updates (that is Catalina 10.15.7 and others security updates for Mojave and High Sierra "005" released a couple of days ago)
Do we need to manually change some catalog? If so, how? Any help will be greatly appreciated
Many thanks Have a great weekend

PS
Also installinstallmacos.py now reports UNKNOWN builds and choosing option "6"
