motor system configuration

Hi, all,
I'm quite new with enigma2 system and I can't configure my motorizes system.
Tha antenna is aligned. I can see astra and hispast with other receptor.
What am I doing wrong?
A)
in the menu/search service/tuner advance/astra( lnb1, no usals, memory 01)
positioner setup / tune to 11109H, movement/ search east or west, antenna moves, astra localized and i store memory.
Out of menu and astra is seen with no problem at all.

When I try to store another satelite I do the same,
menu/search service/tuner advance/hispast ( lnb2, no usals, memory 02), save.
positioner setup / tune to 12092V, movement/ search west, and no movement al all whatever I do.

Out of menu, antenna satys in 0º and no more astra.
If I want to see something, I must restart receptor and A) again.

What is wrong?

the box it's an Octagon sf8 (two weeks old)
Image it's an openatv 4.2

Hi,
Too many thanks for your help.
Unfortunatelly, it didn't help. Keeping the LNB 1 number, the result is the same.
the sequence of operations is like this:
- I program, search and see channels of the first satellite and it's OK
- I program, search and see channels of the second sat, and OK
- When I choose to see the first one, antenna moves to 0º and stays there. In order to leave the 0º, I must delete one of the satellites and reprogram the other.
I already updated the software from the manufacturer, new image but the result is always the same.
What about that???

Hi,
box has no tuner B, just A
I didn't want, but i'll try usals
thank you for the effort.
