In workouts with recurring intervals and a target rpm on the first part of the interval (see below), both in Zwift and on my Wahoo Roam v2 the target rpm from the first part is also shown for the second part. Because this is a problem on both platforms I suspect an issue with how the workouts are exported.
Example:
3x
1m 85-95% 90-100rpm
3m 55-65%
