Garmin Edge 510 Updates Wrecking my power data

Hi, I have just noticed that after a Garmin Edge update my crank arm length resets to 110mm while I use standard 172.5mm. I use Garmin Vector 2 pedals for power data and what I cannot establish is: Does the shorter crank arm result in less or greater power?

Has happened me a few times, the good news is that its significantly under reporting power.

approx. uplift => 172.5/110 = 1.568
