moving system text influences position of lyrics in next staff

in the appended score the system text "Vers 1" (almost on top) appears at a wrong position. When I move the text (using the mouse) to a lower position, the lyrics text of the 2nd staff (What will I...) jumps to a higher position. It rests there, even if I undo the action.
I get the same behaviour with system text "Chorus" (bottom of page 1) and "Vers 2" (2nd page).
