Using a Measure to Combine Multiple Columns into one Card

Hello there,

I am attempting to build a dashboard that would require me to combine multiple columns of data to provide more detailed breakdowns of each section. 

Each column has only 3 expected outputs as this is stored in a sharepoint list, and the type of column is "Choice" meaning they can only choose "Yes" "No" or "NA"

For this report "Yes" and "NA" are considered a PASS and "No" is considered a FAIL.

To do this, I took the approach of making 3 Measurements:

ClientCountYesAndNASpecific = 
        SUMX(
        'Deskside QA',
        IF(
                'Deskside QA'[Didtheresourcefollow-upwit] IN {"Yes", "NA"} || 
                'Deskside QA'[Didthetechnicianpracticethe3Stri] IN {"Yes", "NA"},
            1,
            0
        )
    )

ClientTotalSpecificResponses = 
    SUMX(
        'Deskside QA',
        IF(
            NOT(ISBLANK('Deskside QA'[Didtheresourcefollow-upwit])) || 
            NOT(ISBLANK('Deskside QA'[Didthetechnicianpracticethe3Stri])),
            1,
            0
        )
    )

ClientPercentage = DIVIDE([ClientCountYesAndNASpecific], [ClientTotalSpecificResponses], 0) * 100

In theory, ClientCountYesAndNASpecific would only count "Yes" and "NA" responses, ClientTotalSpecificResponses would count all rows, and ClientPercentage would calculate the percentage of "Yes" and "NA" in comparison to "No"

When I put this into practice however I get unexpected results:

For example:
These 2 tables are the Column Source Counts:

165 lines total 
No = 16
All Lines =165
Meaning the expected output is 90.3%

Instead, this is what I see:

Does anyone know where I'm messing up on this? I have tried a few different ways around this but end up right back where I started.
