Strange "tail" on square shape in Word to PDF documents when printed

For some reason, if I make a Word document, convert it to PDF, then print the PDF, the squares from the Word document get a “tail”. I’ve tried it on different printers and had the same results. Any idea why this occurs?

And here’s what it looks like when printed:
