Issue with Measure Behaviour

[PK_PBIBoss]

I have this base table that gets change or Revised value on basis of what if parameters :- 

Financial Item	X	Account Mapping	Account
Results before Tax	-2.705454625	Tax	Results before Tax
Tax	10.39512275	Tax	Tax
Tax Rate	-3.84228316	Tax	Tax Rate
Results after Tax	-13.10057737	Tax	Results after Tax

Why X + slicer measure  changes its value on addition of field under rows :- JFYI 6.62 is correct version:- 1st version is correct.

Is the issue as we are trying to refer to value Results before tax causing all the circular reference causing the error

Measure :- X+ SLicer :- =

VAR Topup_NetInterest = 'Net Interest Parameter'[Net Interest Parameter Value]

VAR Topup_Fee = 'Fee Parameter'[Fee Parameter Value]

VAR Topup_Other = 'Other Income Parameter'[Other Income Parameter Value]

VAR Topup_OI = Topup_NetInterest + Topup_Fee + Topup_Other

VAR Topup_Exp = 'Total Expense Parameter'[Total Expense Parameter Value]

VAR Topup_RC = 'Risk Costs'[Risk Costs Value]

VAR Topup_RBT = Topup_OI - Topup_Exp - Topup_RC

VAR Topup_LA = 'Lending Assets Parameter'[Lending Assets Parameter Value]

VAR Topup_CRWA = 'CRWA Parameter'[CRWA Parameter Value]

VAR Assumed_TaxRate = 0.14

VAR CT = CALCULATE(SUM(T1[X])+ Topup_OI - Topup_Exp - Topup_RC,WB_APAC[Financial Item] = "Results before Tax")

VAR CT_C = ([RBT_Measure]+ Topup_OI - Topup_Exp - Topup_RC) * Assumed_TaxRate

RETURN

SUMX(

'T1',

IF('T1'[Financial Item] = "Results before Tax" , 'T1'[X] + Topup_OI - Topup_Exp - Topup_RC,

IF('T1'[Financial Item] = "Corporate Tax" , CT_C,

IF(T1[Financial Item] = "Tax Rate", Assumed_TaxRate,

IF('T1'[Financial Item] = "Results after Tax" ,CT - CT_C,

'T1'[X]

)
