Acrobat PDFMaker - Outlook issue

Hello

I am using Adobe PDFMaker in Outlook 2016. I am converting emails into a PDF via the plugin. However some of the emails in Outlook are read receipts. When looking at the read receipt emails in outlook it has the correct date, however when I convert them to a PDF, the plugin alters the date of the email to the current date. How do I fix this to show the correct email and not todays date? This only affects read receipt emails, not any other email types. Thanks!
