Current behaviour:
When applying a configuration through an extension the configuration 'features>content-metadata-presets>custom>exclude' is ignored. Only the excluded properties from a single configuration take effect.

Expected behavior:
All excluded properties from all configurations are applied.

Steps to reproduce the issue:
Create a new extension for ADW with a config file. Alternatively add a new configuration file to be included that will be applied.
Add the following config:

{
  "features": {
    "content-metadata-presets": [
      {
        "custom": [
          {
            "includeAll": true,
            "exclude": [**Include properties/aspects to be excluded**]
          }
        ]
      }
    ]
  }
}

The exclude in the above config will not be applied.
