Hey @gwizzy!
I did some digging and found an answer for ya 
The reason why this is happening has to do with how the rest level is set for the workout.
Intervals that have any section under the rest interval will not be considered for the intervals table on the Ride Analysis Page, so they won’t prompt an in-ride Interval Summary once its completed, and the white power ball won’t appear either. However, the good news is that all ramps are counted towards the total effort, they are just not appearing on the Intervals Summary.
We’ve fixed this problem for Summa Ri workout, so if you complete the fixed version in the future the missing ramps should show on the Interval Summary.
