these blocks should not work if it is a clone and it is local. REASON: you cannot hide them unless you right click it from the stage.
OR: you could just make it when the clone is deleted the lists hide for that clone.
This means (without anything stopping the lists), a project with cloning, it shows the local list, you cannot hide it if you are a viewer, if you are editing you can.

Maybe this would fit better in the feedback forum since you aren't directly reporting a bug but instead suggesting a feature? Or did you have a bug occur because of the fact that you can't show/hide the lists properly?
