Distinct Count - How to get correct row level figures?

Hello,

I'm struggling a lot with this : Calculating a distinct count at the row level doesn't seem to work. Only the total is distinct.I have a table that aggregates a list of accounts by dimensions (region / industry / acc class / motion ).

Im aggregating at the subsidiary level so there's duplicate values. Hence the Distinct Count.

Small example here (real world has more columns) : 

Expected outcome - each row when summed equals the distinct count total

I have tried already the following measure but that doesn't seem to change the row level value.

Test_Distinct = 

VAR T  = SUMMARIZE(_MAL,_MAL[GEO_LEVEL1], _MAL[Region Lvl 2 NA], _MAL[PE MOTION V2], _MAL[PE_SAP_MASTER_CODE_TEXT], _MAL[Internal Account Classification (PE)], "PE Distinct", DISTINCTCOUNT(_MAL[PE_ID]))

RETURN

SUMX(T,[PE Distinct])

Appreciate any help
