No channels found on some transponders of the Astra 3

[krieken]

I have a Topfield Tf7700.
I have a problem by searching for tv-channels on some transponders of the 23.5 satellite, the Astra 3.
In totally there are found only 210 channels on the complete Astra 3
For example transponder 11739V, 11856V, 12129V and 12188H no channels found. All of them 8PSK and DVB-S2.
I tried a lot of things so solve this problem. Before with older AAF-images I don’t have that problem.
Today I found a solution for this.
When I do a manual search and I change the parameter “Pilot” from "auto" to "on" or "off", the channels are found.
But I must do that for every transponder.
Is it possible to change “Pilot” by automatic search? Is it possible to change that in some cfg file ? Pilot in englisch or navigatie in dutch.

I have the same problem with 36E on HDMU_12369_E2_topf_215_git_2865_nodebug_mix.
Is there any solution how to fix DVB-S2 8PSK scanning?

Found solution: just need to add on sattellites.xml list pilots and roll-off

transponder frequency="12572000" symbol_rate="1786000" polarization="1" fec_inner="3" system="1" modulation="2" pilot="0" rolloff="2"/>
