Total using SUMX() and calculated table is not correct

In the filter these is no join with

SumByClaim[ClaimNumber],
            SumByClaim[ClaimantID]

Is it by design. You should take them in group by and also have max measure of SumByClaim[ClaimNumber],SumByClaim[ClaimantID] to join in filter clause as per need. Think that as second table, you need to put join clause to match dates.
