Hi,
Universal App campaign stats are available only through limited reports listed here, and Campaign Performance report in the list. This said, the report should return Universal App campaign stats. So I can further investigate the issue, could you provide the following information via Reply privately to author?
Regards,

Hi,
I have responded to your email address privately. However, if you missed or you haven't received it. You may refer to the response below:
"Thank you for providing the CID and the complete report definition.
Upon checking your account, the campaign which you have there is the type of app engagement campaign. Unfortunately, the AdWords API currently does not support app engagement campaigns and statistics for these campaign types would not be returned by any of its current report types. You may follow our blog for any upcoming features and updates.
Please let me know if you have further concerns."
