Plotmaker Master sizes

[Anonymous]

I am printing a selection of Layouts in PM (but not entire Layout Book)When I select layouts with different Masters which appear to have exactly the same settings (see attached image), and pick "print Selected Layouts in Navigator" and go to Print Options it tells me that the Layouts have different sizes, and does not give a preview of my drawing on the sheet. Any ideas why?
As you can see on the attached screenshot they both have the same sheet size (A3) and margins. Master A3 is my standard drawing title block, and A3 Landscape SK is used for my cover sheet.

Spot the difference....

Thanks, Link, and everyone else for your responses to what initially started as a "curiosity" rather than a real issue. I have used the same masters (from my LBK template) in other jobs and not come across this before, so was puzzled by the message, while still able to actually print.

Thanks again.
