I'll readily agree that LNB configuration is quite cumbersome - I
started to look into what was going on behind the scenes some weeks
ago but real life meant I didn't get as far as I wanted. Hopefully
I'll have a little more time in the next couple of months to pick up

With regard to your issue, try this approach and let me know if it helps:

i) add the DVB-S card and add the LNB, but leave it as unconnected
ii) create a video source, but do not scan for channels
iii) attach the video source to the DVB-S input on the Input Connections section
iv) go back to the card setup, and edit the LNB settings, which should now stick
v) go back to the video source, and you should be able to scan for
DVB-S channels
