It doesn't sound like you are getting any benefit from placing these headers and footers on the master page, so maybe you should just create them on the document pages instead.
Master items are generally considered things that you only override on rare occasions. If you had a unique header or a footer for each of the chapters in your book, you might make copies of your master page for each chapter and only assign each master to that one chapter. In that case, you could move a left page to the right and not have a problem, as long as it was still in the same chapter.
The page title, which is centered, is layering on top of the Master "template" header from page 3 on if those items had been overridden...
It sounds like the page title goes on a page that has no header. If that's correct, you should apply a master to that page that doesn't have a header, the way you might apply a master without a page number to a title page.
You are handling these headers and footers wrong. They have not be to be overwritten in ANY CASE. It breaks the logic. On the page no item from the master has to be editable, otherwise you would not be able to create an PDF which is conform to the UA standard. Elements from the page are part of the content from the master not, as it will be visible on EPUB export or PDF/UA when it comes to read loud out.
Even if your target is print only, where it would not be visible this difference, it is important to follow those rules.
Use these placeholders on the master and fill them with text variables, text generated from text from the page, or from the section information or or or, there are a way lot more possibilities to avoid overrides. Without overrides it is not a problem to shuffle pages around and you will not loose anything. And most important: your exported PDF can be conform the UA standard and an exported EPUB (I don't talk about fixed layout) will show up correctly in most epub readers.
