I am using titleps to get custom headers, and biblatex for the bibliography. The headers look all right except when it comes to the bibliography, where a "REFERENCES" label appears in the header and footer. Here is a MWE:
\documentclass{article}
\usepackage{lipsum}
\usepackage{titleps}
\newpagestyle{fancy}{
\headrule
\sethead[\normalsize \thepage][][]
{Author}{Document}{\normalsize \thepage}
\setfoot[][][]{}{}{}
}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{A2013,
author = {Author, A},
title = {A nice paper},
journal = {Journal},
year = {2013},
volume = {1},
pages = {1--2},
}
\end{filecontents}
\usepackage[style=numeric,backend=biber]{biblatex}
\addbibresource{\jobname.bib}
\begin{document}
\pagestyle{fancy}
\lipsum[1]
\cite{A2013}
\clearpage
\printbibliography
\end{document}
And here is the output:

The left page is ok but not the right page. Where does the "REFERENCES" label come from?
Note that this does not happen if I use bibtex instead of biblatex for the bibliography, or fancyhdr instead of titleps to customize the headers. For instance, replacing lines 3-9 in the example with
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhead{Document}
\fancyhead[L]{Author}
\fancyhead[R]{\normalsize \thepage}
\fancyfoot{}
\fancyfoot[C]{}
\renewcommand{\headrulewidth}{0.5pt}
\renewcommand{\footrulewidth}{0pt}
gives the expected output:

How can I obtain the same result with titleps and biblatex?
