Problems with Denison on the Common App?

Hey y’all,
I’ve been having some problems with denison on my common app. I am trying to assing this coach to be a reccomendor for me, but it wont show his name so I can’t assign him. I can assign him to other colleges, but Denison wont work. Also, it is important to note that Denison does accept coaches for these types of reccomendations.

No specific advice, I recall my kid had trouble adding extra recommenders at various schools, not specifically Denison. I think it had to do with the recommender “accepting” the invitation to submit a recommendation, don’t know if that might be relevant for you.
