If you do not have to use this template, do not use it. See https://en.wikibooks.org/wiki/LaTeX/Scientific_Reports

Do not make any changes to the class file. If you do, you must rename it.

Add the following three lines to the preamble to get what you want. There is no need to change the class file. The class was designed to be customizable to the end user. The option chapterinoneline is not default and needs to be commented out.

\renewcommand{\chapteralign}{\centering}
\renewcommand{\chapterfont}{\Huge\bfseries\MakeUppercase}
\renewcommand{\thechapter}{\Roman{chapter}}

and in the document body use

 \chapter{{Wombat}}

(note the extra craces).

Alternatively, one could use at a later point

\renewcommand{\thechapter}{\arabic{chapter}}
\renewcommand{\mdtChapapp}{}{}
\renewcommand{\chapteralign}{\raggedleft}
\renewcommand{\chapterfont}{\color{black}\huge}
\renewcommand{\chapterinbetweenskip}{}{\vspace*{0pt}}
\renewcommand{\chapterprefixfont}{\fontsize{56pt}{0pt}\selectfont\color{mdtRed}}

\chapter{Alpaca}

to get the following result:
