See attached screen recording.

I can understand adding an exercise to a superset if it is moved to the middle of the superset (i.e. below the first exercise or above the last exercise in the superset). But adding an exercise to a superset when you place it below a superset seems like a bug.

As the recording shows, you then can't remove the exercise without the next exercise being sucked into the superset. Ultimately, one has to unlink the superset and then recreate it with the desired exercises.

Maybe there's a reason it works this way. But thought I'd point this out just in case.

Thanks :))))
