Activity App (watch and iPhone) display duplicate workouts (i.e. two cycling distances of 33.2 miles)

I understand how the Apple Health app prioritizes sources from Apple Watch, iPhone, or any other 3rd party apps and if there are duplicates then it will use the one listed highest in the order of preference. However, despite this, when I look at my Apple Watch I will often see two duplicate workouts in the Activity App. So when I'm scrolling through my activity (Move, Exercise, Stand) then near the bottom it may show that I did two cycling workouts of 33.2 miles when in reality there was only one.

Why does the Activity App on the Apple Watch (and within the Activity App on iPhone) still LIST two workouts even if it appears that the ecosystem as a whole is appropriately tallying data from just one workout source (i.e. my calories don't appear to be double-counted). The only way I can stop this behavior is by unchecking the "workout" option for one of the sources. But, this is not ideal because there may be times when I don't have the other source on and would like to rely on the source that is usually the back-up (#2) option.
