Fill Format for Page Styles Works Then Doesn't

[Gruff18]

Good morning, hope you are all well.

I have a large (novella) document that I need to change to First Page style - I had been doing it using Insert Manual Break then selecting First Page for the style.

Discovered the Fill Format but it's really strange, it only seems to work after I save the doc, go from F.P. to select Default, then F. P. again. It's taking even longer than my original method.

Is there a quicker way to change page sizes, possibly all at once?

Thank you in advance.

The quickest method is the usage the Page Styles.
What a file type are you using? Always use the native, international standard ODF file types (.odt in this case) for the Apache OpenOffice and LibreOffice.
The binary MS document format (.doc) can not handle the Page Styles.

Note that First Page Style uses Default Page Style as a follow on style. It might be simplest to change that follow on style to First Page Style, then apply the amended First Page Style to the first page in the hope that the First Page Style will ripple down through the file

Edit: You may need to remove any inserted Page breaks in the file first
