Pondpack can't insert "pond outlet", only "pond outlet entrance". Can't attached composite structure.

Pondpack is only allowing me to insert a "pond outlet entrance" and not a "Pond Outlet". I built a "composite outlet structure", but can't assign it to the pond, since I can't input a "pond outlet". In the layout tools, when I select a "pond outlet", the program inserts "pond outlet entrance" element instead.  In the properties, I don't see an option to reference my composite structure. Using 08.11.01.56.
