Ahoj, potřebuju poradit s chybou, která se mi vypisuje při použití balíku "tikz" společně s balíkem "babel".

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[czech]{babel} %nelze pouzit! (vadi mu spec znak |- )

\usepackage{amsmath} % nice math symbols
\usepackage{bm} % bold math

\usepackage{tikz}
\usetikzlibrary{arrows} % for arrow heads


% TikZ styles for drawing
\tikzstyle{block} = [draw,rectangle,thick,minimum height=1cm,minimum width=2cm]
\tikzstyle{sum} = [draw,circle,inner sep=0mm,minimum size=5mm]
\tikzstyle{connector} = [->,thick]
\tikzstyle{line} = [thick]
\tikzstyle{branch} = [circle,inner sep=0pt,minimum size=1mm,fill=black,draw=black]
\tikzstyle{guide} = []


\begin{document}

  \begin{tikzpicture}[scale=1, auto, >=stealth']
    \matrix[ampersand replacement=\&, row sep=0.5cm, column sep=1cm] {

      \node[guide] (u) {}; \& 
      \node[branch] (u1) {}; \& 
      \node[block] (F1) {$F_1$}; \& 
      \node[guide] (y1) {}; \\
      
	  \& \& 
	  \node[block] (F2) {$F_2$}; \& 
	  \node[guide] (y2) {}; \\
    };

    % now link the nodes
    \draw [line] (u) -- node {$u$} (u1);
    \draw [connector] (u1) -- (F1);
    \draw [connector] (F1) -- node {$y_1$} (y1);
    
    \draw [connector] (u1) |- (F2); % !!! zde problem s usepackage[czech]{babel} !!!
	\draw [connector] (F2) -- node {$y_2$} (y2);

    
  \end{tikzpicture}

\end{document}

Na označeném řádku mi pdflatex při použití balíku babel hlásí několik chyb. Přikládám i část výpisu logu.

! Use of \@next doesn't match its definition.

If you say, e.g., `\def\a1{...}', then you must always
put `1' after `\a', since control sequence names are
made up of letters only. The macro here has not been
followed by the required stuff, so I'm ignoring it.

I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.

I've inserted something that you may have forgotten.
(See the < inserted text> above.)
With luck, this will get me unwedged. But if you
really didn't forget anything, try typing `2' now; then
my insertion and my current dilemma will both disappear.
