"custom_type" field isn't filled when using Platform API endpoint /users/{userId}/ban

The response I receive when querying the “banned channels for user” endpoint (https://sendbird.com/docs/chat/platform-api/v3/moderation/listing-banned-users/list-channels-where-a-user-is-banned) does not populate the custom_type field, although the dashboard lists the returned channel with a value for it.
