The used module (scm accreg) is not present in any header.
This holds for other modules as well.

Not sure if I'd call it a bug.

You could workaround with instantiating the module in every header:

\version "2.22.0"

#(use-modules (scm accreg))

\header {
  #(use-modules (scm accreg))
  title = \markup \discant "1"
}

\score {
 { c4 d e f}
 \header {
      #(use-modules (scm accreg))
   subtitle = \markup \discant "1"
 }
}

\markup \discant "1"

Tedious, but working.

Cheers,
