Unexpected detection of Duplicate label in \NewDocumentCommand

[NemoYuan2008]

Pre-checks*

• The issue has not been reported in this repository.
• The issue remains after disabling all other extensions and restarting Visual Studio Code.
• The FAQ cannot address the issue.
• The issue is not related to compiling a document, or the document can be successfully compiled in the OS terminal but not in Visual Studio Code with this extension.

Environment*

• Operating System: Ubuntu 22.04.4 LTS
• Visual Studio Code Version: 1.88.1
• LaTeX Workshop Version: 9.19.2
• TeX Distribution Version: TeX Live 2024

The Issue*

A warning Duplicate label #2 is reported in the following example for \NewDocumentCommand, which is unexpected.
In contrast, \newcommand works well.

Similarily, \NewDocumentEnvironment has the same issue.

\documentclass{article}

\newcommand{\cmda}[2]{\section{#1}\label{#2}}   % Good
\newcommand{\cmdb}[2]{\section{#1}\label{#2}}   % Good

\NewDocumentCommand{\cmdc}{mm}{\section{#1}\label{#2}}  % Duplicate label #2
\NewDocumentCommand{\cmdd}{mm}{\section{#1}\label{#2}}  % Duplicate label #2

\begin{document}
\cmda{1}{1}
\cmdb{2}{2}
\cmdc{3}{3}
\cmdd{4}{4}
\end{document}
