Viewing Markups from other formats

My co-worker and I use PDF’s to proof documents and I use the Kami extension because I like it so much. My co-worker, on a Mac, uses her Mac programming. When I send her a Kami-marked up document, she has no problem seeing my notes. When she sends me her marked-up document, I can only see some of her notes.

When she highlights something and leaves a note, I can only see the highlight, but the note. Is there something I should be doing to see all the markups?
