I lose my alphabet

[Denis Penard]

Hello,

It seems there is a slightly weird thing over here about alphabet!

My alphabet should be A B C D E F G H I J but when I run the part below, 
it is wrong.

I had the same for another score.

Let's see:


\version "2.22.0"

\score {

  \relative {
    \time 4/4
    \set Score.markFormatter = #format-mark-box-letters
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
  }
}
\score{
  \relative {
    \time 4/4
    \set Score.markFormatter = #format-mark-box-numbers
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
    R1
    \mark \default
  }

}
