Music symbols not displayed correctly

I digitalized "Hauptsatzkantate" by Friedrich Wille:

https://musescore.com/user/34397346/scores/6214019

On page 6 under bar 26 one sees the text "Wiederholen von (segno sign) bis A, dann Coda", in English "Repeat till (segno sign) then coda". But this music symbol is not displayed correctly anymore. I am afraid that this bugaffects song texts as well. There you also have to display fourth and eigth pauses in the text.

You only see this very symbol correctly if you download this musescore file.
