WAD - Export to Excel Issue

Hi Gurus,

We are encountering strange situation. When we perform export to excel feature in WAD reports the excel export works sucessfully, however the sheet on which the data is exported names itself to "Recovered_Sheet1". However when we perform export to excel for a query launched through a query designer it works fine and the sheet is names as "Report(some numbers). We are on SP 13 & SPS11 for BI Java. Please advise

Thanks!
