I'm not sure what's causing it, but I can suggest a couple of things to try...

1. Comment out the line Application.CutCopyMode = False and see if it
runs as expected. I have seen other cases where this command caused problems
(you got from the macro  recorder, right?)

2. Tell Excel explicitly which workbook and worksheet to use, either by fully
qualifying the ranges:
ThisWorkbook.Sheets("Whatever").Range("D33:K34").Select
or by issuing commands to make sure the correct workbook and worksheet are
active:
ThisWorkbook.Activate
ThisWorkbook.Sheets("Whatever").Activate
before the range commands that are being misdirected.
