RANX gives duplicates and skips numbers when filter is applied

[gspollock]

I am requesting assistance on a report that is supposed to rank the Sales data. There is a slicer on the SECONDARY column.  When SECONDARY = N, the data has only one row for each CUST NUM/CUSTOMER combination.  When SECONDARY = Y is included in the data, there are multiple rows for each CUST NUM/CUSTOMER combination.

The RANKX seems to work correctly when SECONDARY = N. When either Y or both Y and N are selected in the slicer, it is giving duplicates for some rows that aren't identical and skipping some ranks.

This is the function: Rank Current = RANKX( ALLSELECTED(DIM_CUSTOMER[CUST NUM], DIM_CUSTOMER[CUSTOMER]), FACT_SALES[SALES],,DESC,Dense) 

Here is a portion of the underlying data.  

CUST NUM	CUSTOMER	ACCOUNT MANAGER	SECONDARY	SALES
390429	Customer11	Account Manager10	Y	774933
390429	Customer11	Account Manager11	Y	774933

Thanks for your assistance.

Hi lbendlin ,thanks for the quick reply, I'll add more.

Hi @gspollock ,

Try this

Measure = SUM('Table'[SALES])

Measure2 = RANKX(ALLSELECTED('Table'[CUST NUM],'Table'[CUSTOMER],'Table'[ACCOUNT MANAGER],'Table'[SECONDARY]),[Measure],,DESC,Dense)

Final output
