QuotChap パッケージの問題

Question

私は章を美しくするためにパッケージを使用していますquotechap。問題なく動作していますが、問題はコンテンツと参考文献のセクションで発生します。私のコード

\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}

これを使用すると、コンテンツの見出しが右上の奇妙で不適切な場所に配置されます。これを修正する方法がわかりません。
