S3 bucket PDF files can't be accessed using virtual hosting style links

Hi there, I have a static website being hosted in an S3 bucket with Route 53 handling redirects to our short URL and everything is working well (I'm able to use relative paths in the HTML for pages, images, CSS etc.) except for with PDF files. For some reason, the PDF files can't be accessed using virtual hosting style links (such as http://www.townepoint.org.s3-website-us-west-2.amazonaws.com/images/newsign3.JPG) and only path style links (such as http://s3.us-west-2.amazonaws.com/www.townepoint.org/TPOA+Commons.pdf) work. This is breaking the ability to reference the files relatively like all of the other files on the site. Using the examples above, http://www.townepoint.org/TPOA+Commons.pdf is not a working URL when http://www.townepoint.org/images/newsign3.JPG does work.
