Remove 'active contents' from PDF file that was converted from LaTeX?

I recently rewrote my CV in LaTeX using Overleaf.com. Once I finished writing my CV in LaTeX, I downloaded it as a PDF. I'm now trying to upload my CV on brassring (careers website) and every time I select the PDF file I get the following error: 'The system does not allow files with active contents.' However if I try and upload my original CV that was written in Word it successfully uploads.
