Easy header question

Hi. I can’t for the life of me find out why Libreoffice is doing something:
What happens is when I make a header and have “Running header: Title (page number)”
then click “not same first page”
Then I want just “Title (page number)” for the rest of the pages…
For some reason just the first and third pages have the same page number. And the rest have 2 as the page number.
I’ll redo anything you say to fix this.
What is the easiest way to do standard APA “Running header: Title” on the left and page number on the far right.
Then on the rest, just the title and continued page number on the right.
Thank you for the help.
