The Other Recommender section only appears if a college allows at least one type of Other Recommender. But not every school accepts all of the types. Some colleges have selected to only accept certain types of Other Recommenders. If the Other Recommender type that you have invited is not accepted by the college, you will not be able to assign them to that college
