If this message is not eventually replaced by the proper contents of the document, you PDF viewer may not be able to display this type of document.

Hi, Okular uses the Poppler library to load PDF documents, so you should report the problem to its bug tracking system, at https://bugs.freedesktop.org "poppler" product. This looks like acrobat using javascript to place content on the document, so in case unlikely it can be fixed easily. Thanks for the report.
