(Urgent) Export problem with PDF

Hi,

I have a problem I've never had before:

  • Exported a 2 page design to PDF, usual settings. 
  • Detailed floral pattern, curves, no outline, color only
  • Pattern on page 1 is messed up. Shows up in PDF like pictured below (Left side)
  • Pattern on page 2 is correct. (Right side) 

Tried:

  • Copying pattern from page 2 to page 1, still the same
  • Creating new layers and copying ''good pattern'', still the same
  • Tried looking into export settings, nothing unusual.
  • Tried looking if i have any effects on the page, none.

Does anyone know what the problem is? CorelDRAW X7
