Deleting "First page" format

Hi,
I’ve tried to find a way to change “first page” format to “standard” format w/o success.

So, my document page 1 is defined as “first page” and page 2 and further is defined as “standard page”.
How do delete the “first page” format from the document?

Are you using the native, international standard .odt file format?

Then apply the “Default page” style to the first page what has the “First page” page style now.

Can you upload a sample file here?

Thank you for your suggestion but “default page” doesn’t work for the header settings

Please upload a sample document here. (Delete the sensitive content from a copy of your document.) We need the applied page style structure only.

To change the format/style of the first page, go to the first page. The footer bar of LibreOffice shows several areas, e.g. “Page x of y”, number of words and characters, and the current page style. The latter likely reads First Page.

Right mouse-click on “First Page”. A context menu appears that shows various page styles. Choose the new style from the menu, for example Default Style:
