Custom_field_data doesn't work for Playlist query

Hello,
I added custom properties (custom_field_data) to the content so that they would appear in the widget.
When I try to get a Playlist with content (query in the file), the content is always returned with a null Custom_field_data. 
Is it possible to correct the returned result, that if I request a playlist, then the custom data should also be returned?
