Letter of Recommendation on Common App problem?

I have invited a “other” recommender on my common app and she has submitted it. I’ve assigned her to multiple colleges on my list, however when I go to the recommenders and FERPA section of my tufts application, instead of saying “add a recommender” and letting me assign her, it says “invite a recommender” and won’t let me use her’s even though she has already submitted it. How do I fix this problem?
