Reference to a figure

Question

When referring to a figure, the output in my pdf is not a number, but 'Figure xx'. For example: if I use the phrase

This is figure \ref{test}.

the output in my pdf file is always:

This is figure Figure 1.3.

I would like to know why LaTeX shows the prefix 'Figure' and not simply the number of the figure. Here is the general code that I use for a figure:

\begin{figure}[h]
    \centering
    \includegraphics[scale=0.9]{Test.eps}
    \caption{Test}
    \label{test}
\end{figure}

Interestingly, when referring to a subfigure, this issue does not occur; it only occurs when I want to refer to a 'whole' figure. As my document is quite extend (thesis), I use a lot of packages in my preamble, but even after an extensive quest I could not figure out what the problem might be.

My preamble:

This is caused by chemstyle package, and to be more precisely by the varioref option. Set it to false if you don't need it.
