SSRS Multi Parameter Report not working in Sharepoint 2013

I have a report which has 2 Parameters both are multi select. It works fine in SSRS Reporting Manager and Report Builder but when I host in SharePoint and try to select multiparameter it doesn't do anything. Do we need to make some setting change in SharePoint to accept multiparameter or this is an issue with SSRS and SharePoint combination. Appreciate any help.

Thanks
