A phantom mile added to my workout (it happens couple of times a year)

I've had the watch since early 2021 and I've never encountered this, but I rarely do planned workouts. My guess would be is that your workout is set in a certain way which results in this bug. Maybe try deleting that particular workout and setting up another and seeing if it happens again.

This happened to me just today. My workout was a scheduled 8 mile run, with no other steps and no targets (no goal pace or heart rate). At the end of my run map data looks good, but laps has an extra mile in between 7 and what should be 8, with a time of 1193 hrs. 

I am in the Beta program, and have never seen anything like this before. Garmin, if you're reading this, please fix! 

I've just had this bug, first time.

Planned workout, I had done 10km , training was finished, as soon as I hit pause it read 11km.

Very same here, 2nd time this week on Vivoactive 4s, on planned workout run.

How it that possible to get Garmin attention on this? I already think of throwing my watch out of the window. Please note also sourrounding KMs time are wrong! This makes workout statistics completely irrelevant.
