I'm wondering, too!  I'm having the same issue...it's showing that I have  "gross pay-this is not a legal pay stub" on my P&L under wages and this amount is the gross amount.  Then there is an expense for the net amount.  It has completely screwed up my books.  I know I can't delete the gross pay entry because that will delete it from the history so I'm not sure how to correct it.  This is for Quickbooks Online.  I think the example provided was for Quickbooks Desktop, maybe?
