Problema Impaginazione Capitoli

Ciao. Io ho un problema di impaginazione dei capitoli della mia tesi.
Ho impostato

`\usepackage{geometry}
\geometry{a4paper,tmargin=2.5cm,bmargin=4cm}`

Per il primo capitolo non ho problemi, per i seguenti me li posiziona decisamente più in basso nella pagina.

Il codice del documento principale è il seguente:

Vi prego di aiutarmi perchè mi mancano pochi giorni alla consegna della tesi e sono disperato.
Grazie a chiunque mi dia un contributo.
