Dynamics CRM 2011 reports filtering problem

Hi,

I have a weird issue using report filters.

I have created some reports using visual studio 2008 and using sql connection to database (FilteredViews).

I used the prefix CRMAF_FilteredAccount to enable prefiltering on the report.

When i click run report on "Account X", the report runs and give me the information of "Account X". I click on edit filter and change the filter to Account-->Equals--> "Account Y", click Return to Report and click refresh and again i get the information of "Account X". It seems all report will not refresh the filter when i edit it.

Any clue what might be the problem

Thank you for any help
