Layer Confusion

Hello - hope someone can assist with advice.

A client sent me a .pdf from a design they created in Photoshop.

Their font files are corrupt so I'm importing as curves and just retyping the text.

My concern is, when I publish to pdf to send to the client for approval, some information disappears.  I've added a new layer, I've moved things to the back and things to the front, yet, nothing works.  There are no invisible items - only the guidelines.  Everything is viewable and printable...
