Garmin Edge 540 Issue with Vo2Maxt

Hi guys

I've been using garmin edge for a while now. I noticed that there seems to be a bug with Vo2Max.

At first I though it was just a normal because after changing from 530 to 540 my Vo2Max suddenly changed from 60 to 59.

But until now it seems no longer passing to 60 like it stuck at 59.

Best regards,

Irvin
