P-Nucleo WB55 USB Dongle Stack Programming Problem

[OrnellaBenzi]

I own 2 P-Nucleo-WB55 boards and dongles. I was able to program the FUS, Stack and FW in both Nucleo boards, but now I want to do the same with the dongles but I cannot program the FUS or the Stack in none of them. 
* In one of them I get:
FUS status is FUS_IMAGE_NOT_FOUND
Warning: Firmware upgrade Error!
when trying to upgrade the stack to the stm32wb5x_BLE_Stack_full_extended_fw.bin at 0x080C7000 (in this dongle i was able to upgrade the FUS to the last version (1.2.0) using the CubeProgrammer CLI )
* In the other dongle, I tried using the CubeProg GUI , but when trying to upgrade the FUS or the Stack I got 

FUS status is FUS_IMAGE_NOT_AUTHENTIC
Error: Firmware not authentic!

The same error got using the CLI. Althought I couldn't upgrade the FUS, when pressing Read FUS Infos I get that the FUS version is 1.2.0 (but no FUS Operator).
Also, sometimes using the GUI I got Device Desconected error when upgrading either the FUS or Stack.

CubeProgrammer v2.19
Stack v1.22
FUS v1.2.0
Extra info: I am able to correctly flash "normal" firmware in the CM4.

Can anyone help me?

Hello @OrnellaBenzi and welcome to the ST Community

Could you please send the screenshots of all your option bytes values for both dongles and the current version for stack and FUS of both boards (on screenshot from the GUI) (specify the concerned board for each screenshot).

Best Regards.

Here are the screenshots you asked (Dongle 1 is the firs mentioned above, with the Warning, and Dongle 2 is the one with the Not authentic error):
