Expected:

• only show each media recommendation once
• use the same meta-data for each instance of the same media recommendation; in the above example, genres and MAL rating are different for what should be the same item)
• when adding items, keep the same sort order; the two identical items should be adjacent in the sequence, helping the author to find duplicates before publishing
