Octave mangOH yellow - yellow_wp77xx_0.4.0-octave.spk Octave reports "The firmware deployed on this device is not official""

I loaded https://downloads.sierrawireless.com/mangOH/spk/yellow_wp77xx_0.4.0-octave.spk

The backend is reporting - “The firmware deployed on this device is not official”

Any ideas?
