Content Editor bug/limitation? - Some attributes can't be cloned

While creating a tuning pack in the editor there are some attributes that can’t be cloned such as the tuning_simulation (for whatever reason the clone function is greyed out). As a result this prevents us for changing some parameters that we would like to change (e.g fishing regeneration rate/amount etc).

Is this intended? or is it because the editor is still considered in beta?

This is intended, though is in discussion. I honestly have no idea what the timetable is for any editor updates. Wish I could be more help, but unfortunately that’s all I got.
