When I built my plan, I replaced Thursday’s interval session with a Zwift race. After the completed Zwift activity sync’s back to TR, I associate the activity to the Zwift race placeholder on my calendar. Today I noticed that the Zwift race is being classified as a sweet spot session. I looked back at previous Thursday Zwift races and they are also classified as sweet spot sessions. The TR workout is different each week: Truchas, Eichorn, Tallac…

Is this a bug or a feature? 😅

This is a visual bug. That sweet spot workout is what your Zwift race would be replaced with each week, if you toggled it back to being a TrainerRoad workout.  
I’ll take a look at why this is displaying this way. Thanks for pointing it out!
