It seems I have a problem with the headers using the book
class. On every chapter when the text is too long the chapter text and the section text merge. Also I don't know how I could make them lower case instead of upper case.
The packages I use can be seen below:
\documentclass[12pt,oneside]{book}
\usepackage[english]{babel}
\usepackage{graphicx}
\usepackage{natbib}
\usepackage{appendix}
\usepackage{microtype}
\usepackage[utf8]{inputenc}
\usepackage[english]{isodate}
\usepackage[parfill]{parskip}
\usepackage[colorlinks,pagebackref,pdfpagelabels=true,plainpages=false]{hyperref}
\usepackage{fancyhdr}
\usepackage{makecell}
\usepackage{amsthm}
\usepackage{pdflscape}
\usepackage{multirow}
\usepackage{mdwlist}
I then include each chapter like this:
\begin{document}
\input{title.tex}
\tableofcontents
\input{overview/overview.tex}
\input{background/background.tex}
\input{chapter1/chapter1.tex}
\end{document}
Here is a bit of code from background:
\chapter{Introduction to Simulation}\label{part:background}
\section{A Simple Example}\label{sec:sim_example1}
There is of course content in between. First page of the chapter seems fine however second page of the chapter produces the text below but mangled. It looks a lot better below.
2.1. A SIMPLE EXAMPLEPART 2. INTRODUCTION TO SIMULATION

The package fancyhdr needs some code after loading it, in order to define precisely what goes in the header.
In oneside format it's not very common to have both the chapter title and the section title, because the header will be too crowded. You probably have somewhere the declaration
\pagestyle{fancy}
, otherwise the setting would be the standard, that prints on the header only the chapter title and the page number:If you want the section title and the page number in the header, then
If you want the chapter title, change the fifth line into
There's no practical way to make chapter and section titles to coexist, except to put them on two lines.
