Cubase 8 - Xml export issue


I am using the score editor in Cubase, and I would like to export the score using Xml into Dorico or Sibelius 7. My problem is that for every page break I have in Cubase (score editor - page mode), both Dorico and Sibelius create new clefs for all the instruments. I have attached two screenshots, of both Dorico and Sibelius, to show the problem.
I am on Cubase 8.5, MacOS El Capitan.

Anyone has the same problem? Any advise?
