Hello,
For the title of the chapters I use the following command.

\unexpanded\def\HeadTitle#1#2%
   {\framed
      [frame=off,
       width=fit,
       align=flushleft]
       {\color[darkgray]{\tfxx\cap\bf\labeltext{chapter}}
        \blank#1\blank#2}

When I compile my project, I have the label "Chapitre" above the word "Sommaire" in the table of contents : how to delete it ?

1. Don't apply the command to \title

\setuphead[title][command=]


2. Make the command local to bodypart of your document, this works only when you use section blocks (e.g. \startbodymatter)

\startsectionblockenvironment[bodypart]
    \setuphead[chapter][command=\HeadTitle]
\stopsectionblockenvironment
