Displaying StaffGroupBar after tweak

[Karim Haddad]

Dear All,

I have this problem:

I customize staffs using the following tweak:

kHide = {\hideNotes
                \stopStaff
          \override TupletBracket.transparent=##t
          \override TupletNumber.transparent=##t
          \override Staff.BarLine.transparent=##t
          \override Staff.Clef.transparent=##t
          \override Staff.StaffSymbol.line-count=#1
          \startStaff
        }

kUnHide = {\unHideNotes
            \stopStaff
            \revert TupletBracket.transparent
            \revert TupletNumber.transparent
            \revert Staff.BarLine.transparent
            \revert Staff.Clef.transparent
            \revert Staff.StaffSymbol.line-count
            \startStaff}


Whenever there is a pagebreak (explicit or automatic), the StaffGroupBar 
disappears.
I know i am missing something here.
Here is a somehow not so moderate MWE (sorry):

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.24.1"

#(set-default-paper-size "a4landscape")
#(set-global-staff-size 18)
\paper {
    system-system-spacing = #'((basic-distance . 15) (padding . 20))
     system-separator-markup = \slashSeparator
    #(define after-title-space (* 0.5 cm))
    #(define head-separation (* 0.5 cm))
    print-page-number = ##t
    print-first-page-number = ##t
    first-page-number =#1
   top-margin = 2\cm
   bottom-margin = 3\cm
         two-sided = ##t
   inner-margin = 20\mm
   outer-margin = 20\mm
%%%%%these come together:%%%%
    %left-margin = 20\mm
    %line-width = 380\mm
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%  
}



kHide = {\hideNotes
                \stopStaff
          \override TupletBracket.transparent=##t
          \override TupletNumber.transparent=##t
          \override Staff.BarLine.transparent=##t
          \override Staff.Clef.transparent=##t
          \override Staff.StaffSymbol.line-count=#1
          \startStaff
        }

kUnHide = {\unHideNotes
            \stopStaff
            \revert TupletBracket.transparent
            \revert TupletNumber.transparent
            \revert Staff.BarLine.transparent
            \revert Staff.Clef.transparent
            \revert Staff.StaffSymbol.line-count
            \startStaff}
