Interval comment gets overwritten - swim erg workout

When I create a swim erg workout the rest interval comment (I put “rest”) gets overwritten by the comment above.
I first create the workout with sets and reps check box being checked. Then I go and type interval comments.
Then when I go back to the workout editor and check “Sets and reps” box again (if I want to modify the duration of multiple intervals then this overwrites the rest interval comments.

I think it works, it just hides the colum when you switch to interval comments and back.

I think your screen recording uses bicycle workout creation. Please try swim workout.
Try this: create an interval with the rest. Enter a comment into a rest and then got back to sets&reps and add additional interval. then take a look at the comments you earlier entered into the “rest”. those comments will be overwritten
