Percentage total is being calculated incorrectly in matrix (Using Drill down)

I have 2 columns 'Total OPD Visits' and 'EMR Filled'. I must calculate 'EMR Usage %' as 'EMR Filled'/Total OP Visits'.
Here's how my matrix is set up:

The numbers on the 'Practitioner' level are correct. However, on the specialty level, it is just adding (or averaging) the practitioner-level numbers.

SPECIALTY:

PRACTITIONER:

Currently set to average.

I want the specialty numbers to be the correct division, i.e. [EMR FILLED (for all practitioners under that specialty)] / [TOTAL OPD VISITS (for all practitioners under that specialty)].

I have tried various solutions presented by the community on similar issues:

EMR USAGE DETAIL% = 
DIVIDE (
    CALCULATE (
        SUM ( Detail_Conversion_Report[EMR_Filled] ),
        ALL ( Detail_Conversion_Report[Specialty], Detail_Conversion_Report[Practitioner] )
    )
    ,
    CALCULATE (
        SUM ( Detail_Conversion_Report[Total_OPD_Visits] ),
        ALL ( Detail_Conversion_Report[Specialty], Detail_Conversion_Report[Practitioner] )
    ),
    0
)


// SUM('Detail_Conversion_Report'[EMR_Filled])/SUM('Detail_Conversion_Report'[Total_OPD_Visits])

// CALCULATE(DIVIDE(Detail_Conversion_Report[EMR_FILLED_MEASURE], Detail_Conversion_Report[TOTAL_OPD_MEASURE]),
// ALLSELECTED(Detail_Conversion_Report[Specialty]))

// CALCULATE(DIVIDE(Detail_Conversion_Report[EMR_FILLED_MEASURE], Detail_Conversion_Report[TOTAL_OPD_MEASURE]),
// ALLSELECTED(Detail_Conversion_Report[Practitioner], Detail_Conversion_Report[Specialty]))

// IF(HASONEFILTER(Detail_Conversion_Report[Practitioner]),
