Branding Settings are not returned by the Channel's List API

Youtube's Channel's list API isn't returning brandingSettings even when requested explicitly like this: https://www.googleapis.com/youtube/v3/channels?part=brandingSettings&id=UCJ-gg-0xws8J6PKfY6DBLzg&key= returned this:

{
 "kind": "youtube#channelListResponse",
 "etag": "\"XI7nbFXulYBIpL0ayR_gDh3eu1k/hqQ5f5obTKYUNURbAaBo87W-LAw\"",
 "pageInfo": {
  "totalResults": 1,
  "resultsPerPage": 1
 },
 "items": [
  {
   "kind": "youtube#channel",
   "etag": "\"XI7nbFXulYBIpL0ayR_gDh3eu1k/EEjleDhJYQadoLAXlnHS41MfcRk\"",
   "id": "UCJ-gg-0xws8J6PKfY6DBLzg"
  }
 ]
}

I wonder if this is a problem or will it be permanent to change?
