Descent G1 PO2 Issue - incorrectly shown

So my Descent G1 Solar is incorrectly displaying the PO2, either at the surface, or at depth.

When I check the PO2 at the surface (sea level) for pure oxygen, it's showing as 1.03, in addition, the MOD is showing as 3.7 meters despite me setting the max PO2 as 1.4, which should be 4 meters.

This might not sound like a big difference, but for us technical divers, an incorrect PO2 is an issue and can seriously affect deco times. Whilst we're primarily following the written plan, contingency plans can involve the use of the computers calculations - so it needs to be correct.

Things I have checked:

The altimeter is correctly calibrated

There are no weird storms in the area affecting the pressure.

The issue affects both single gas and multi gas dive modes

I'm running the most up to date software (17.02)

This issue was pointed out by someone else around 2 years ago, and I'm surprised there has not been a fix as of yet. For reference, my Shearwater Teric displays it correctly, i.e 1.00 Bar at the surface, MOD of 4m etc. 

Garmin - please can you respond to this potentially dangerous issue?
