Answer 1

Es sieht so aus, als ob der Knoten titlerecdas Rechteck sein soll, das mit dem ersten \fillBefehl erstellt wurde. Wir können dies durch einen Knoten ersetzen, indem wir dentikz fitBibliothek und die Seitenknoten vonAbonnierenum das Problem zu lösen.

Der folgende Code wird nun fehlerfrei kompiliert und liefert die gewünschte Ausgabe. Natürlich wurde die harte Arbeit zunächst im Post erledigt.https://tex.stackexchange.com/a/374634/134144. Dennoch habe ich den Code rationalisiert, besser genutztAbonnieren, habe die nummerierten und die nummerlosen Versionen konsistent gemacht und Code entfernt, den ich für unnötig hielt. Sobald dies erledigt ist, erzeugt der Code:

Hier ist der aktualisierte Code:
