Hi Pooja,
Please check Id and CreateBy Attribute value in FamilyMembers. It contains default value as 0.

You are applying below filters in DashBoardApplicant screen aggregates. So make sure that FamilyMembers.CreatedBy contains logged in user Id -

On SubmitApplicationOnClick you are only creating Family members and on DashBoardApplicant screen aggregates you are using Applicant table.


Thanks
Vinod
