Ok, I think I see what's wrong. Your settings are fine (satellite name, device, etc). You should not click on places on the graph where there is not a distinctive signal peak. In your screenshot there are only 8 useful peaks where you can click, the other part of the graph is mainly ripples from your LNB, or the card itself. Nothing useful there. See the attached screenshot, I marked with green arrows the peaks where you can click and with red where you should not click.
Btw. Since there is nothing in your graph from 10700 - 11700 you may set your frequency range for this satellite from 11700 - 12750 or even from 11700 - 12200 if there is nothing to receive above it in your region.
