I don't think it's working correctly, either on the site or through the API. Is this a known issue?

Using the following data:

{media_type: 'movie', media_id: 11, watchlist: true}

activates my profile as expected.

However, when using this data:

{media_type: 'movie', media_id: 11, watchlist: false}

it should logically remove the movie from my favorites or watchlist, but it doesn't seem to be working at least my profile don't get updated
