Track Run with Workouts skipping steps, creating ghost laps and adding fake distance

Fenix 6S - Software: 25.10

The last two track run sessions I have run, I have used a workout with repeats. Each time the workout step changes from run step to the recover step as I cross the start line the watch automatically skips the recover step. The intervals recorded on the FIT file are all wrong and if I manually skip the step it adds ghost laps and fake distance and crazy personal best records (and excluded segment efforts on the Strava upload).

The first time I noticed it I had a 400m autolap trigger. The second time I took off autolap and the problem reoccured. This hasn't shown with the same workout on a normal run. It is making the watch unusable for one of my main use cases.

This didn't occur on 17th January on Software: 24.10.

Is this a known bug? Any ideas?
