Syncing of 'copied' workouts in TrainingPeaks

I’ve observed on several occasions now training peaks workouts not syncing into zwift. If i create a workout from scratch in trainpeaks, it will sync in zwift successfully.

Though if I then copy this workout (or any previous workout) and paste it into today’s date or a date in the future, the workout will never sync if zwift (either today or if i wait for the date of the planned workout).

The workouts do sync successfully onto my wahoo bolt each time, so I believe it might be a bug with zwift.

The workaround is to create each workout from scratch to ensure it syncs to zwift correctly. This is slightly annoying when i have about 4 go to workouts I use.

Has anybody else observed this issue??
