Export colors don't match colors in the file - pdf, jpg, tiff & eps

I have a file created (originally in x5). I am now using x8. I have edited to all cmyk colors and in a cmyk document and the right profiles. The colors shift when export.

What is causing this? See images. I have been using Corel for over 20 years and have never seen this. I have had this issue in x7 and x8.
