PDF Exporter does not export template property information from the page linked to the exported page

Hello,
I do have ExportPage which contains a link to [[Page1]]. The Page1 is created from template and contains several properties which are already filled with appropriate data. Now, when I export Page1 alone, PDF exporter correctly exports all property names and their values. But if I export ExportPage with &includelinks=2 in a hope that it will also export Page1 just below the ExportPage content, this does not work, i.e. Page1 properties names and values are not exported. Please note that Page1 content alone (text) is exported as expected. So the problem is with export of properties' names and values...
