I encountered a problem with my ToC using APA style. The title appears twice in the table. I tried several things, but I believe it is concerned with the use of the apa6 document class. Help would be greatly appreciated.
\documentclass[a4paper,man,natbib]{apa6}
\usepackage[english]{babel}
\usepackage[utf8x]{inputenc}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage[colorinlistoftodos]{todonotes}
\usepackage{hyperref}
\usepackage[T1]{fontenc}
\usepackage[usestackEOL]{stackengine}
%excel2latex
\usepackage{multicol}
\usepackage{multirow}
\usepackage{booktabs}
%\usepackage{titlesec}
%\titleformat{\subsection}[runin]
%{\normalfont\bfseries}{\thesubsection}{1em}{}
\title{\LARGE Example Title}


apa6class is designed to meet the requirements for submitting to APA journals. It's probably not an appropriate class for a thesis. But you can adddonotrepeattitleto the class options to remove the extra title. – Alan Munn Feb 08 '18 at 15:40
