How do I reset the goals in the workout app to default 'open goal'?

Some of the workouts have changed from 'open goal' to 'cal'. I want to keep all workouts as default 'open goal'. Does anyone know a way to reset this?

I know you can click on the 3 dots icon and then select open goal from there - but this adds another 2 clicks, which can be annoying/tricky if you're changing activity on the move.

Any solutions - or why it does this? (some other posts suggests OS automatically changes default based on previous workouts)
