On receipt printout, wrong date of printout

Hello All, Using UM 16.04

Just noticed the other day that when I print out a receipt from Amazon, The date is wrong in the bottom right hand corner. It’s been dating all receipts 12-31-69.

Is there something I can do about this? Should I contact Amazon?

This makes it a little hard to go back to around a certain date of purchase, to look up info.

Thanks
