Data field showing on every sales invoice page despite asking it to display on last page only

Hi,

I am thinking this is more of a glitch as I (think) am aware of the solution but it doesnt seem to be saving my request.

I have since added a data box to our sales invoices showing (applied) amount. However on multiple page invoices this amount shows on every page - yet the freight and total does not appear (which is what I want)

Been on the "fields" tab > data field > ticked "applied" > appear at end of form > ok > save template

I go back on the form and it is appearing on the bottom of every page again!  Am I doing something wrong?

Many thanks
