The zone colour is controlled by the settings for your zone categories.
You can create Graphic Override rules that make zones transparent, or have a solid foreground or background fill, etc.
There should be standard rules already set up, but if not have a look in the standard template and export them so you can import them into your files.
I would be guessing that in plan you are using a GO that is making the zones transparent.
But in the views that you are printing, they are using a different GO where the zone colours are showing.
