Macro/Page Setup Issue - Converting Excel to PDF

I created a form that co-workers can use to do a used evaluation on farm equipment. In this form I created an Email As PDF button. It basically converts the form to a PDF and attaches it to an email that already has the TO: and SUBJECT: lines filled out. It usually works great, but recently someone found an issue. When they use this button, the PDF version sometimes ends up like the attached "Incorrect" pdf instead of the "Correct" pdf. Anyone have any ideas what's going on?

If you would like to look at the Excel workbook, please message me with an email address - the file is to large to upload here.

Thank-you for any insight!
