[NTG-context] bug in MarkIV ? section numbering

Dear all, the following example : ... \chapter{Blabla} \subsection{bla} ... is numbered 1 Blabla 11 bla The problem appears only if I "skip" the \section step. In fact \chapter{Blabla} \section{Bla} \subsection{bla} gives 1 Blabla 1.1 Bla 1.1.1 bla Is the first example the expected behavior ? I would better have think to something like 1 Blabla 1.0.1 bla Best, Amaël
