Cycling VO2 Max

Hi, everyone,

I've been getting frustraded with garmin lately. I track my rides through MyWoosh and simultaneously with my Forerunner as an indoor bike activity. After that, I use a fit file editor (Gotoes website) to merge the two files into one, including that the activity was done with the Garmin Edge 1030 Plus device and marking it as virtual ride. This way I can get all the metrics in the final file, like training load, training status, power, heart rate, etc. However I cant get cycling vo2max measurements. Even though I have GPS data from MyWoosh and simulate the Garmin Edge as my device.

Does anyone know what else I need to do to get my cycling vo2max measurements? The vo2max field stays empty despite having all the required data like power and heart rate with the GPS track.
