Make the "no lists added box" empty
When choosing a list to add to a module in the hierarchy the default should be that the box is blank and not showing the title of the first list of your My Lists.
In the attached example you can see Behaviour Change appears in the box because it is first in My Lists - however it is not attached - and quite misleading.
We released some changes to how lists are linked to the hierarchy node. It now utilises a search box, which also allows you to link draft lists.
