When I tag a property from a reference module the module number id is missing and this is make setting up complex scenarios very confusing.
Welcome to the Make community!
To show module IDs, simply right-click the canvas of the scenario editor, and select “Show module ID”
Hope this helps! If you are still having trouble, please provide more details.
