Visual total correct but rows dont add up

Hi

In my visual below I am showing the Balance as at Feb20 my first column and the movement amounts in the next 3 columns.

The grand total for the movement columns are correct, and the sum of the rows for these columns add up to the correct grand total.

However, for the balance column, the rows dont add up to the grand total which is the correct amount i.e. 10.2m is the correct total, but the sum of the rows for the balance column is like 2m. It is like there are rows missing..

Please can you advise? See detail below.

Here are my Measures: 

FAC Claims Debtors move:=CALCULATE(SUM('RICLAIMSDEBTORS'[AmountInclVAT]),RICLAIMSDEBTORS[RI Type Group]="FAC")

FAC Claims Debtors close ALL:=
VAR CumulativeTotal = CALCULATE([FAC Claims Debtors move],
FILTER(ALL('SSAS V_DIM_AccountingPeriod - ReportingPeriod'),'SSAS V_DIM_AccountingPeriod - ReportingPeriod'[ReportingDateEnd]<=MAX('SSAS V_DIM_AccountingPeriod - ReportingPeriod'[ReportingDateEnd]))
)
RETURN
IF(ISBLANK([FAC Claims Debtors move]),BLANK(),CumulativeTotal)
