Tab Ultra Note pdf export changes format

Hi,

i imported a PDF to the noteTemplate, it size /format ist 210 mm x 297 mm.

Now using it as an template an writing some stuff and when i startet the export to pdf or sending it on dropbox, the generated pdf has a new size 495,3x660,4 mm.

I can print it by reduzing size (44%) in acrobat reader but in future i need it on regular size. Is there any solution for my problem?

Sorry, my english isn´t the best. Greetigs from EU
