Intention only working once in an editor cell that should accept multiple concepts

Hi,  I have a concept that can come in two forms, both of which extend a common ancestor. So in theory when I am in the model and I am in the cell that accepts the ancestor and I press Intention, I should get both possible concepts, and this does work, but only once, afterwards there is no more intention available, and pressing Enter just fills in the second form of the concept, and I am not sure what I am doing wrong.

Here you can see the intention suggested and the editor accepted the first form enclosed in {}, but after that there is no intention available and it defaults to the second form.

This is the second form of the concept, that I am having trouble with.

This is the first form

The definition of the concept I am working with in the solution
