QuotChap 套件的問題

Question

我正在使用該包quotechap來使章節變得漂亮。它工作正常，但問題發生在內容和參考書目部分。我的程式碼

\documentclass[a4paper,11pt,twoside]{report}
%\usepackage[utf8]{inputenc}
\usepackage[a4paper]{geometry}
\geometry{verbose,tmargin=1in,bmargin=1in,lmargin=1.25in,rmargin=1in}
\usepackage[autostyle]{csquotes}
\usepackage[dvipsnames]{xcolor}
\usepackage[labelfont=bf]{caption}
\usepackage{emptypage}

%\usepackage{mathrsfs}


\usepackage{titlesec}
%Underlining ruler for subsections
\titleformat{\section}
  {\normalfont\Large\bfseries\color{black}}
  {\thesection}
  {1em}
  {}
  [{\titlerule[0.8pt]}]

\usepackage{amsmath,amsfonts,mathtools}
\numberwithin{equation}{section}
\linespread{1.3}
\usepackage{quotchap}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\renewcommand{\chapterheadstartvskip}{\vspace*{-4\baselineskip}}
\begin{document}
    \input{abstract.tex}
    \addcontentsline{toc}{chapter}{Abstract}
 \clearpage
%%%%%%%%%%%%%%%%%%% Table of contents %%%%%%%%%%%%%%%%%%%%%%%%%%%%
\tableofcontents
\pagenumbering{arabic}
    \include{ch1}


\vspace{-4.0\baselineskip}
\textbf{\begin{flushright}
        {\LARGE \textbf{BIB}}
\end{flushright}}
\vspace{-0.5\baselineskip}
\noindent\rule{\linewidth}{2pt}
\bibliographystyle{abbrv}
\renewcommand{\bibname}{}
\bibliography{thesisref}
\end{document}

使用此功能，內容標題被放置在右上角一個奇怪且糟糕的位置。我不知道如何解決它。
