Well it turns out that after reviewing the model... We don't need a many-to-many relation.
A user can only have one "service." So I changed the model and made the attribute
and relation be "serviceLevel."
So things work now. Though now I have that little irritating lingering question about
if "services" is a reserved word or .... ?
I remember having an issue years ago because I named a component "Request."
That cost me hours upon hours... lol... changed the name and voila that worked.
