Your SP field indicates that you are performing Data Reduction when someone opens your document. Administrators become ordinary users in the AccessPoint (a problem they do not have when you open your document as Administrator in QV Desktop) and since the Data Reduction reduces your data to nothing at all, you will not be granted access.
Gysbert's suggestion will work to get the QDS reload up-and-running. Another solution for the reload would be to include the service account of the Distribution Service in your section access table. Then reload manually and try again in the QMC.
