Strange Behavior of Spinner Up/Down Buttons, Multiple Event Firings

I have a spreadsheet where I can enter a date in either of 2 ways:
1) manually type in a date;
2) click an ActiveX Spin Up and Spin Down button which triggers an event to increment up or down by 1 day.

If I change the date manually, it produces the desired result of triggering a Worksheet_Change Event which causes the spreadsheet to do some computations and display the resulting data and some charts.

However, if I increment the date using the Spinner Button, it triggers 20+ Worksheet_Change Events which does the calculations 20+ times.

I have spent 2 days trying to debug this line by line and cannot find any reason that this would be happening. The triggering event is the same, i.e. the value in a cell gets incremented by 1. How can the spinner button make such a difference?

Is there a known bug with these controls which could produce such drastically different results?

Here is the code for the Spin Up Button:
Code:
Private Sub SpinButtonDate_SpinUp()


Debug.Print "SUB SPIN UP"


Dim TargetSelection             As Range
Dim Col                         As Long
Dim Row                         As Long


    'Application Settings
    Application.DisplayAlerts = False
    Application.EnableEvents = False
    Application.ScreenUpdating = False
    Application.Calculation = xlCalculationManual
    
    Dim rowNewValidDate                 As Long
    Dim NewValidDate                    As Date


    'Validates the Date and then Increment Date to Next ValidDate
    rowNewValidDate = Application.Match(CLng(Range("B1").Value), WSLists.Range("C:C"), 0) + 1
    NewValidDate = WSLists.Cells(rowNewValidDate, 3).Value
    Range("B1").Value = NewValidDate

        'Update Dashboard
        Call UpdateDashboard(DashboardRow)
    End If
    
ExitSub:


    'Enable Settings
    Application.DisplayAlerts = True
    Application.ScreenUpdating = True
    Application.EnableEvents = True
    Application.Calculation = xlCalculationAutomatic


End Sub
