Is there an existing issue for this?

I have searched the existing open and closed issues

Current Behavior

When a release is downloaded, if the release name does not match the movie name and a language custom format is in use then the unknown movie item is not displayed in the Radarr queue. Show Unknown Movie Items is selected.

Here's the json for the lamguage custom format I'm using:

{
  "name": "Not Original Language",
  "includeCustomFormatWhenRenaming": false,
  "specifications": [
    {
      "name": "Not Original",
      "implementation": "LanguageSpecification",
      "negate": true,
      "required": false,
      "fields": {
        "value": -2
      }
    }
  ]
}

Expected Behavior

The unknown movie would be displayed in the queue.

Steps To Reproduce

Setup a language custom format (eg, the example above)
Ensure Show Unknown Movie Items is checked in the queue options
Download a release of a movie where the movie name does not match any known name for that movie
Wait for the download to finish
Observe that the unknown movie does not show in the queue
Delete the language custom format
Refresh the queue
Observe that the unknown movie now appears
