StartRow argument ignored when importing a .csv

Hello, I'm following the "Automated Text Import in Excel with File Selection - The Easy Way - VBA" tutorial. I've gone through and completed the example with the various components and am now trying to build it to my specific purpose. I generated a .csv in another program and would like to import this, skipping the first (header) row. The tutorial shows a way to do this which works for me with the example .txt file, but when I import my .csv file (after changing the delimiter to comma) the header row is still included (see screenshot included). Can anyone tell me where I'm going wrong?

Select All
Sub Import_File()

    Dim FileToOpen As Variant
    Dim fileFilterPattern As String
    Dim wsMaster As Worksheet
    Dim wbTextImport As Workbook
    
    Application.ScreenUpdating = False

    fileFilterPattern = ".csv Files (*.csv), *.csv"

    FileToOpen = Application.GetOpenFilename(fileFilterPattern)
   
    If FileToOpen = False Then
        MsgBox "No file selected."
    
    Else
 
        Workbooks.OpenText _
                Filename:=FileToOpen, _
                StartRow:=2, _
                DataType:=xlDelimited, _
                Comma:=True
   
        Set wbTextImport = ActiveWorkbook
        
        Set wsMaster = ThisWorkbook.Worksheets("Raw Data")
        wbTextImport.Worksheets(1).Range("A1").CurrentRegion.Copy wsMaster.Range("A3")
    
        wbTextImport.Close False
    
    End If
    
    Application.ScreenUpdating = True

End Sub
