Aurora R15, BIOS 1.22.0 gives Unknown Command error

Hi all,

I am trying to update my Aurora R15 from BIOS 1.17.0 to 1.22.0 and getting the error "Unknown Command" from the BIOS Flash Update screen. I downloaded the 1.22.0 directly from the DELL website. Why is this happening or anyone actually successfully ran the update? 

DELL Support getting an error processing BIOS update as well.

Can't see with that pop-up, but it looks to me like aurora_R15_1.14.1_X64.exe in the files section.
