Almost all of my activities I track with my Garmin Vívosmart 4 are cycling. This is all tracked correctly and the data attributed to cycling in the "All activities" section of Garmin Connect Reports.
However, if I go to the section "Cycling" in Garmin Connect Reports right below "All activities," all of the data is NULL 
: Hence my VO2-MAX for cycling is 0, my FTP value is NULL, my Normalized Power is NULL and so on.
Despite the fact that Garmin Connect obviously attributes my activities to cycling, the "Cycling" reports section does not contain any data.
What steps can I take to try to remedy this problem?
