    Hi anthonjhnon1  , You can update the measuer to use remove filters from the dim table 

    CIs Test 2 = 

VAR CIs = CALCULATE(SUM(Fact[TotalCustomersAffected]),REMOVEFILTERS('Major Event'[Major Event]))
VAR NonME_CIs = CALCULATE(SUM(Fact[nonME_CI]),REMOVEFILTERS('Major Event'[Major Event]))
VAR MajorEvent = SELECTEDVALUE('Major Event'[Major Event])

VAR MENo = NonME_CIs
VAR MEYes = CIs - NonME_CIs

RETURN
SWITCH(
    MajorEvent
    , "y", MEYes
    , "n", NonME_CIs
    , CIs
)

The issue is that variables in DAX aren't really variable, they're constants. They are only ever evaluated once, so trying to evaluate them again with a modified filter context will not work, they will still have their original value. If you need to change the filter context then you need to include the full definition of the variable again inside the calculate.
