I was able to resolve this issue by adding "accessible to public" form on my entity editor (which I would like to recommend be the default in the CollectiveAccess theme if possible in the future, for ease)
To do this:
Manage -> Administration -> User Interfaces -> Standard entity editor -> Screens -> Basic Info
From the left "Available editor elements," move "Entity access" to the right "Elements to display on this screen."
Hope this helps for anyone else who was having trouble with entities showing up!
