Consolidating Worksheets issue

Im having two issues

Issue 1) at the top of my "IMPORT" sheet its duplicating the header name in A1 so that it is appearing twice once in cell A1 where it should be and in A2.
Issue 2) I want to change this to actually pastes values into the "Import"

Here is my code

Sub Merge_Sheets()

Dim startRow, startCol, lastRow, lastCol As Long
Dim headers As Range

'Set Master sheet for consolidation
Set mtr = Worksheets("IMPORT")

Set wb = ThisWorkbook
'Get Headers
Set headers = Worksheets("ImportM1").Range("A1:K1")

'Copy Headers into master
headers.Copy mtr.Range("A1")
startRow = headers.Row + 1
startCol = headers.Column

'loop through all sheets
For Each ws In wb.Worksheets
     'except the master sheet from looping
     If ws.Name <> "Import" And ws.Name <> "Paste Here" And ws.Name <> "M3" And ws.Name <> "M2" And ws.Name <> "M1" And ws.Name <> "Vlookups" And ws.Name <> "Validation" And ws.Name <> "Fail" Then
        ws.Activate
        lastRow = Cells(Rows.Count, startCol).End(xlUp).Row
        lastCol = Cells(startRow, Columns.Count).End(xlToLeft).Column
        'get data from each worksheet and copy it into Master sheet
        Range(Cells(startRow, startCol), Cells(lastRow, lastCol)).Copy _
        mtr.Range("A" & mtr.Cells(Rows.Count, 1).End(xlUp).Row + 1)
           End If
Next ws

Worksheets("IMPORT").Activate

End Sub
