Cumulative Distinct Count by Day Behaving Incorrectly with Filters

// Please create a proper calendar in your
// model following the guidelines outlined here:
// https://dax.guide/dateadd
// and connect it to your fact table and remember
// that fact tables should always be hidden and
// slicing should only happen via dimensions. If
// you want to get into trouble, ignore the rule.
//
// Then you can write:

[# Distinct ID to Date] =
var CurrentDate = MAX( Dates[Date] )
return
	CALCULATE(
		DISTINCTCOUNT( 'Learner Info Daily'[LRN] ),
		KEEPFILTERS( Dates[Date] <= CurrentDate ),
		ALLSELECTED( Dates )
	)
