Fitness Age from VO2 Max missing?

I recently found out about this metric that is available in the app. I checked to see and there was a single reading only for 9 of August this year. I checked the other periods of time available, nothing else. I thought maybe it was some kind of intense activity on that day and it was able to calculate it. No activity at all that day. I don't do much training or activities, how exactly and when is this Fitness Age number calculated?
