I am using the solution in the following link: How to add an extra level of sections with headings below \subsubsection. More specifically this part:
\documentclass{article}
\usepackage{titlesec}
\usepackage{hyperref}
\titleclass{\subsubsubsection}{straight}[\subsection]
\newcounter{subsubsubsection}[subsubsection]
\renewcommand\thesubsubsubsection{\thesubsubsection.\arabic{subsubsubsection}}
\renewcommand\theparagraph{\thesubsubsubsection.\arabic{paragraph}} % optional; useful if paragraphs are to be numbered
\titleformat{\subsubsubsection}
{\normalfont\normalsize\bfseries}{\thesubsubsubsection}{1em}{}
\titlespacing*{\subsubsubsection}
{0pt}{3.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}
\makeatletter
\renewcommand\paragraph{@startsection{paragraph}{5}{\z@}%
{3.25ex @plus1ex @minus.2ex}%
{-1em}%
{\normalfont\normalsize\bfseries}}
\renewcommand\subparagraph{@startsection{subparagraph}{6}{\parindent}%
{3.25ex @plus1ex @minus .2ex}%
{-1em}%
{\normalfont\normalsize\bfseries}}
\def\toclevel@subsubsubsection{4}
\def\toclevel@paragraph{5}
\def\toclevel@paragraph{6}
\def\l@subsubsubsection{@dottedtocline{4}{7em}{4em}}
\def\l@paragraph{@dottedtocline{5}{10em}{5em}}
\def\l@subparagraph{@dottedtocline{6}{14em}{6em}}
\makeatother

For what ever reason by dots shows up like this:
