I am using \title within frontmatter for an introduction. The \setupheadertexts for title (recto and verso pages) is:

\setupheadertexts
  [{\hfill\getmarking[title]\hfill}][]
  [{\hfill\documentvariable{metadata:title}\hfill}][]

Now, that setup (this time for [chapter]) works correctly for chapters in the main body of text, but for some reason that I am unaware of, in the case of the 'Introduction', I get a header text ('Introduction' is the text) where I should except for the last page of the introduction (There are seven pages in the intro, so it is the 7th, therefore odd-numbered page that is missing the header).

I would like to understand why this is happening and, of course, be able to adjust something so that I do get the header on that page, as I do for the other pages.
