Titletoc appears to truncate part of the title label defined by titlesec

Question

I have the following MWE where I'm adjusting how my sections are rendered using the titlesec package. Based on this question, I came up with the following:

\documentclass{article}
\usepackage{titlesec}
\usepackage{titletoc}
\titlelabel{Article \thetitle: }
\titlecontents
    {section}
    [0pt] % mandatory, sets left margin from left page margin
    {} % above code
    {Article \thecontentslabel} % numbered entry
    {} % numberless entry
    {\thecontentspage} % add dots here if desired, filler page format
\begin{document}
    \tableofcontents 
    \clearpage
\section{Intro}
\section{General}


\end{document}

The section labels look like I expect:

However, the section labels in the table of contents look different:

I'm not sure why this happens. What am I doing wrong?

Answer 1

Follow the description of each argument of \titlecontents that you already have in your code as comments.

So that modifying the command such a way should do the thing

\documentclass{article}
\usepackage{titlesec}
\usepackage{titletoc}
\titlelabel{Article \thetitle: }
\titlecontents
    {section}
    [0pt] % mandatory, sets left margin from left page margin
    {} % above code
    {\bf Article \thecontentslabel: } % numbered entry
    {} % numberless entry
    {} % add dots here if desired, filler page format
\begin{document}
    \tableofcontents 
    \clearpage
\section{Intro}
\section{General}


\end{document}
