It's confusing me, I must admit.

I set the first page margin to 4.5cm (just below the headed paper type header on the first page).

I then goto page 2, no header (just a footer). I adjust the margins on this page to 0.75cm, and set "from this point on onwards". This seems to work, I get different margins for the first page and then onwards.

But when I save and then re-open, the second page margins have reverted to that of the first page (I save the template with just one page, having deleted the lines that fell over onto the second page).

Seems simple, but I am struggling
