Missing Collection after MUP

I’m fairly new to meteor and mongodb. My app works great locally. All my collections in my database work as they should. I used MUP to deploy it to my DigitalOcean droplet. Now, most of my mongodb collections work great. I can insert, query, update, delete, etc, except for one of them. It is a mailing list collection. The form seems to insert into the collection (i.e. it doesn’t return any errors in the console or otherwise, and it acts as it should), however, I can’t find the collection anywhere. I can’t query it, I can’t find it through the mongo shell, nothing.
