A lot of times, files are supposed to be designed a certain way or have content entered a certain way. If Not, then problems may exist!

Transponder information in satellites.xml is expected to be in a certain order. This is the order the blindscan plugin is looking for in a satellite transponder in satellites.xml:
freq, sr, pol, fec, inv, orb, sys, mod, roll, pilot, MIS, pls_mode, pls_code, t2mi
Most of the time in coding, 1 is 0 in a list. So transponder 1in satellites.xml will be coded as 0
Here is the code where blindscan puts together the transponder for starting the dish motor:
transponder = (tps[0][1] // 1000, tps[0][2] // 1000, tps[0][3], tps[0][4], 2, orb_pos, tps[0][5], tps[0][6], tps[0][8], tps[0][9], eDVBFrontendParametersSatellite.No_Stream_Id_Filte r, eDVBFrontendParametersSatellite.PLS_Gold, eDVBFrontendParametersSatellite.PLS_Default_Gold_C ode, eDVBFrontendParametersSatellite.No_T2MI_PLP_Id, eDVBFrontendParametersSatellite.T2MI_Default_Pid)

Here is a satellite transponder from the satellites.xml in TNAP-5.1:
(freq, sr, pol, fec, inv, orb, sys, mod, roll, pilot, MIS, pls_mode, pls_code, t2mi)
<transponder frequency="11718000" symbol_rate="2390000" polarization="0" fec_inner="2" system="1" modulation="2" />


Here is the same transponder from the satellites.xml that you posted:
(freq, sr, pol, fec, inv, orb, sys, mod, roll, pilot, MIS, pls_mode, pls_code, t2mi)
<transponder system="1" fec_inner="2" frequency="11718000" polarization="0" symbol_rate="2390000" modulation="2" />

The first item in the transponder is supposed to be frequency. The first item in your transponder is system. No way this is gonna work!

The Blindscan Frequency Range is recorded by what was being displayed when the blindscan started. I am going to guess you have two or more satellites using slightly different lnb settings, and you were moving between them when doing a blindscan. Fix the satellites.xml problem first and see if this issue is also fixed.
