Problem: Only part of exported pdf can be seen.

Hi,
I tried to export my mindmap as pdf to get it sent to my team member and to get it printed in multiple pages. But when I open the pdf I get a message “The dimensions of this page are out-of-range. Page content might be truncated.” and only part of the mindmap can be seen.

Mindmap including a timeline of 350-page script gets easily quite big. Isn’t it possible to export big mindmaps so that I can share it with the members of my project team?
Best,
J.T.
