SSRS subscription is not visible but is still running.

 I have SSRS integrated with SharePoint 2010.  I have a monthly subscription running on one of my reports, when I logged in last month to check on it, it seemed to have disappeared.  I was confused, but I recreated the subscription (as  best as I could remember).  This month, I get the report twice (with slightly different parameter settings). It looks like the old subscription is still running even though I cannot see it in SharePoint.

 I logged into my SharePoint/RS SQL DB instance and ran this statement:

  DECLARE @myReportFileName varchar(50) = 'MyReport.rdl';
   SELECT
      c.Name
     ,u.UserName
     ,s.* 
   FROM
     dbo.subscriptions s 
     INNER JOIN [dbo].[Catalog] c ON s.Report_OID = c.ItemID
     LEFT JOIN dbo.Users u ON s.OwnerID = u.UserID
    WHERE
      c.Name LIKE @myReportFileName
   ;

I can see two rows in the subscriptions table, with the LastRunTime corresponding to the dates I received my reports.

Both subscriptions are in my name (OwnerID), but as I said before, only one appears in SharePoint under "Manage Subscriptions" for that report.

How can I access this hidden subscription.  If I cannot otherwise access this subscription, can I just delete the extra row from the Subscriptions table?

TIA
