VBA Word: Mail merge labels printing

Hi, I have created a label template in Word and written a macro to print all records (see code below printAllRecords() and attachments) from an Excel datasource. The problem is when I press F2 (defined function key to print all records in my macro), it prints the 1st page once and then print all records (i.e. 1st page is printed twice). Anyone knows why and how to fix it?? Thanks!
