@isazi I have been back and forth with TrainAsOne over that topic, but now it all makes sense to me.
I had a workout planned with a 3.2km step (run as fast as you can) in between, that I couldn’t hold for that distance. So I pressed the lap button shortly after 2km. This didn’t advance the workout as I indended (therefore I contacted TrainAsOne), probably because I wasn’t on the Guide screen.
Back to the topic: In the Suunto App I see all the laps filed in the manual tab. As you see the 3.2km is split into two parts, due to the lap button press.

However, when I’m exporting that activity as FIT file. Fitfileviewer only recognizes two laps - and complains about a corrupt FIT file.

TrainAsOne ignores all lap information anyway, so they aren’t affected by this, but other services are.
On other workouts where I didn’t press the lap button, all workout steps are exported as individual (manual) laps.
I can share files or links, if it helps.
