Naviance - Common App Letters of Rec Troubles

So, I’ll cut to the chase: my last letter of rec came in today, my teacher told me so. I see it on Naviance as having been completed, but when I go and look at the commonapp it’s blank where it should list the recommender. It has worked for my other teachers, and this last teacher is urgent because I mean to apply for the early deadline for tomorrow. Does anyone know how to fix this or make sure that the letter has been successfully submitted? Thanks.
