Application Insights: Profiler Trace Duration messed up

I am looking at application insights and investigating in a performance issue:

-> Application Insights -> Performance -> Select an operation -> Profiler traces

enter image description here

The duration for that operation at the left of the screen is (7462.45 ms) while the total duration of the events for this operation is (15509.03 ms). How could that happen?

The time on the left represents the length of time that the request took according to a "clock on the wall". The length of time on the right is the total CPU time or thread time that the request used. If the request is multi-threaded and work is being done in parallel, more total time will be used than what is represented in wall clock time.

We are working on a UI that will explain this situation better.
