VBA - Code is duplicating paste into column not specified in code - vba

Question

I'm using the below code to copy column B in combinedWorkbook to column B in ThisWorkbook but when running the macro it seems to paste column B into column C of ThisWorkbook as well as pasting into column B. I've stepped through the code and it works fine. This seems very strange and would be grataeful with any help on why it's also pasting into column C in ThisWorkbook.
Sub ImportWriteOffs()
Dim filter As String
Dim caption As String
Dim combinedFilename As String
Dim combinedWorkbook As Workbook
' Open BRAM Report Source Data
MsgBox ("Select 'SRMF0035 BRAM Pre Repurchase'")
filter = "Text files (*.*),*.*"
caption = "Select 'SRMF0035 BRAM Pre Repurchase'"
combinedFilename = Application.GetOpenFilename(filter, , caption)
If combinedFilename <> "False" Then
Set combinedWorkbook = Application.Workbooks.Open(combinedFilename)
Else
MsgBox "No file was uploaded", vbExclamation
GoTo LastLine
End If
If combinedWorkbook.Worksheets(1).Range("D7").Value = "Periodic Insurance" Then
' Copy and Paste into working file
Sheets("Tabular Version").Select
Range("B10:B100000").Select
Selection.Copy
ThisWorkbook.Activate
Sheets("Input - Write offs").Select
Range("B10:B100000").Select
ActiveSheet.Paste
Application.CutCopyMode = False
combinedWorkbook.Close False
' Delete last row
ThisWorkbook.Activate
Sheets("Input - Write offs").Select
Range("B10").Select
Selection.End(xlDown).Select
Selection.EntireRow.Delete
Else
MsgBox "Incorrect File Selected"
combinedWorkbook.Close False
Exit Sub
End If
LastLine:
End Sub

You can try this. Notice that you do not need to .Select a cell to copy it. It defeats the purpose of VBA! Just get right to the point: State the range and copy it. No need to select.
Also, no need for GoTo as mentioned by the infamous #ashleedawg, just Exit Sub when needed.
Sub ImportWriteOffs()
Dim ws As Worksheet: Set ws = ThisWorkbook.Sheets("Input - Write offs")
Dim filter As String, caption As String, combinedFilename As String
Dim combinedWorkbook As Workbook, ws2 as Worksheet
MsgBox ("Select 'SRMF0035 BRAM Pre Repurchase'")
filter = "Text files (*.*),*.*"
caption = "Select 'SRMF0035 BRAM Pre Repurchase'"
combinedFilename = Application.GetOpenFilename(filter, , caption)
If combinedFilename <> "False" Then
Set combinedWorkbook = Application.Workbooks.Open(combinedFilename)
Set ws2 = combinedWorkbook.Sheets("Tabular Version")
Else
MsgBox "No file was uploaded", vbExclamation
Exit Sub
End If
If combinedWorkbook.Worksheets(1).Range("D7") = "Periodic Insurance" Then
ws2.Range("B10:B" & ws2.Range("B" & ws.Rows.Count).End(xlUp).Row - 1).Copy
ws.Range("B10").PasteSpecial xlPasteValues
ws.Range("B10").PasteSpecial xlPasteFormats
combinedWorkbook.Close False
Else
MsgBox "Incorrect File Selected"
combinedWorkbook.Close False
End If
End Sub

This is happening because the select is actually using a relative reference. But it would be clearer what you want to do if you used Cells instead:
For r = 10 to 10000
ActiveWorkbook.Worksheets("Input - Write-offs").Cells(r, 2) = combinedWorkbook.Worksheets("Tabular Version").Cells(r, 2)
Next
You can implement something similar for deleting the last row, if you are so inclined.
