SQL database auditing content pack loads with no data in "AuditLogs" table

I connected to the SQL database auditing content pack using storage account name , server name , database name, table name , start date and end date also provided Account key in the second step , I got a successfull message after loading . I have logs in the storage account i checked it on azure storage .But when i click  reports and dashboard it doesnt have any data to show visuals , all the visuals are empty . I tried doing this a lot many times. Just guide me if i'm doing something wrong.
