Montclair put me on waitlist - they haven't received my portfolio

Hi guys!
I have a quick question.

I applied for Montclair State University’s film making program and was placed on their waitlist for not sending my portfolio in on time. So, after receiving the letter, I filled out my portfolio and sent it in the next day via slideroom. This was a month ago. My application still says that they haven’t received my portfolio.

Does this have to do with the waitlist position?
Or is it a technological problem?
