We're using the extension from SDLTridionWorld to process download links, http://sdltridionworld.com/community/2011_extensions/process-download-links.aspx. We found an issue with the extension where the first anchor in the rendered output is not processed.
We have enabled viewing the debug log and ran the TBB in TemplateBuilder. The extension's log states that it is found, but isn't replaced. We've also tried running it against different PDFs, but the issue persists. What could be the cause?
