Hello Peter,
I hope you're well.
Thank you for bring it to my attention, I love a good challenge. I will look into it further, however I cant see any code on the website that would cause Google to show the date 20161124. Therefore I have come to the conclusion that the problem is a result of the .PDF I was given to upload onto the website. I will looking into it further when I get home and have access to a proper computer. I am currently working on a RPi3, I have patience but not that much.
Kind Regards,
Ashley.
