Task Form do not show Advance Fields on ASP.Net Task Forms

I have a SharePoint integrated Process. On Sharepoint Integration Wizard I have Selected ASP.Net as form Technology, Use Default Pages as Form Location and Basic form as Form Layout. While on Sharepoint Integration Client we have selected Advanced form as Form layout and selected few Data Fields from Action Page. Process is deployed successfuy and starts on item creation in List but when we open task form it shows only basic fields on form no Data Field selected from Action Page is shown.
