Cannot open document link in exported pdf

Hi,
I’m using draw 5.4.0.3 and created a link refering to a page in the same document. If I click in the same draw it works fine but when I export the document as PDF links to internal page don’t work at all. I open with Adobe Reader and it tries to open an URL that is in my computer as I used the export URLs relative to file system. I also tested with Fliphtml5 but same problem.
When I used a previous version it worked but I forgot which one.

Thanks
Angelo
