Page numbering in Writer

My LibreOffice 3.5.4.2 Writer is restarting page number every time there is a Title Level 1 paragraph, and is numbering the pages with odd numbers (1, 3, 5, …) as if they were all right pages, despite my document has only one page type.

If you can’t find anything special in the style properties (see my answer), would it be possible to upload the document (to dropbox, for example) so we can check it directly?

OK, changing the “Page Layout” to “Right and Left” solves the problem of numbering the pages only with odd numbers, but I would like to insert a page break before every “Heading 1” paragraph without resetting the page number, do you know how this could be done?

I’ve emended my answer to cover this issue.

OK, that´s the problem: all individual “heading 1” paragraphs had inherited the page break “with page style” so I hade to change one by one, but now it´s OK. Thank you!
