DAX - Data only populating when I use slicers

Question

I want to return count of employees on a table visual without having to use date filters. But count only appears when I move the date slicer.

date filter selected on slicer no date filters selected

Here are my calculations: SelectedMinDateStart = CALCULATE( MIN('HR Calendar'[FirstDayOfMonth]), ALLSELECTED('HR Calendar')) --Returns date that is first of the month because data is captured at first day of the month.

Starting Roster Active Employee =

/VAR StartDate = MeasuresTable[SelectedMinDate]/

VAR StartDateBegin = MeasuresTable[SelectedMinDateStart]

RETURN

CALCULATE (

    DISTINCTCOUNT('Employee Data Snapshot'[Employee]),



         'Employee Data Snapshot'[SnapshotDate] = StartDateBegin)

--Returns count of employees

I am expecting the counts on the Starting Roster to appear regardless of date filters selected; populating all dates on table with expected counts.
