Laravel morphTo Returns Null

I am using Laravel 5.4 and having trouble figuring out why my morphTo relationship always returns null no matter what I do. The inverse of the relationship is fine, but when I try to retrieve the owner of the polymorphic relation, it is null.

class Opportunity extends Model {

    public function Organization() {
        return $this->morphTo('Organization');
    }

}

class Account extends model {

    public function Opportunities() {
            return $this->morphMany('App\Opportunity', 'Organization');
        }
}

class Department extends model {

    public function Opportunities() {
            return $this->morphMany('App\Opportunity', 'Organization');
        }
}

$org = App\Opportunity::findOrFail(1)->Organization;

The full namespace is stored in the database and the _type and _id actually have the appropriate organization type and id in the columns (i.e., 'App\Account' and '456'). So, I know the database record and the returned Opportunity object have the correct Organization in the columns (I can see it in the database correctly), but no matter what I do, if I try to retrieve Organization it is null.

Here is the output. You will notice the Organization is in the attributes, but the relation is null and I cannot get it to return even adding ->with('Organization') to the query. It doesn't even seem to be executing the query to get the owner
