Header after \listoftables incorrect

Question

I am encountering a very strange error. I have sections from \frontmatter while others from lists of tables, figures etc... however after \listoftables the headers do not change according to the section any more but all show List of Tables. Can anyone help?

\RequirePackage[l2tabu, orthodox]{nag}
\documentclass[oneside]{um} 
\usepackage{blindtext}    
\begin{document}
    \frontmatter 
        \maketitle
        \input{frontmatter/originality}    
        \input{frontmatter/dedication}        % include a dedication.tex file
        \input{frontmatter/acknowledgements}   % include an acknowledgements.tex file
        \input{frontmatter/abstract}\if@openright\cleardoublepage\else\clearpage\fi
        \tableofcontents*\if@openright\cleardoublepage\else\clearpage\fi
        \listoffigures*\if@openright\cleardoublepage\else\clearpage\fi
        \listoftables*\if@openright\cleardoublepage\else\clearpage\fi
        \input{frontmatter/abbreviations}\if@openright\cleardoublepage\else\clearpage\fi

This is the abbreviations frontmatter:
