[Tex/LaTex] Appendix in thesis

appendicesnumbering

I am compiling my thesis in latex and I want to add appendices, but I'm not quite getting it right. In particular the Appendix chapters get the right name for example Appendix A. But sections, figures and tables all get the wrong name. For example the first section in Appendix A is not A.1 but 1.1, which was already a section in the chapter before Appendix A. This is the code I use:

 \documentclass[12pt, a4paper]{book}
 \usepackage[titletoc]{appendix}
 \chapter{bla}
 some bla
 \secion{bla}
 etc
 \begin{appendices}
 \chapter{bla}
 \section{blabla} (This is the culprit being named 1.1 instead of A.1)
 \end{appendices}
 etc etc.

Can somebody help me out? Thank you very much.

As @Mico pointed out: the error does not occur if one makes a working example based on your code:

\documentclass[12pt, a4paper]{book}
\usepackage[titletoc]{appendix}
\begin{document}
\chapter{boa}        
some bla
\section{boa}            % This becomes: 1.1 bla
etc
\begin{appendices}
\chapter{bla}
\section{blabla}         % This becomes: A.1 blabla
\end{appendices}
\end{document}

The result looks like this:
