Edges have blank links

[nkibler7]

I noticed that sails-orientdb seems to put two links on the edge's schema that aren't necessary (since in a graph DB, we have out/in). These links aren't actually populated from what I can tell, so why are they needed at all?

Here's an example of my User schema. Note that the following/followers relationship is on the User class itself, and I confirmed that the placement of the dominant flag is correct because the edge direction makes sense when I do something like user.followers.add().

var User = {
  // Enforce model schema
  schema: true,
  // Change long table names to edge names
  joinTableNames: {
    following: 'follows'
  },

  attributes: {
    // Field attributes
    email: {
      type: 'email',
      unique: true
    },
    firstName: 'string',
    lastName: 'string',
    deleteOn: 'date',

    // Association attributes
    followers: {
      collection: 'User',
      via: 'following'
    },
    following: {
      collection: 'User',
      via: 'followers',
      dominant: true
    }

  }
};

When I view the edge in OrientDB's web interface, I see this:
