Target Language for Regex setting in settings.json

[code-instable]

Defining the regex on langugae specific settings (VScode doc) does not seem to work

"[latex]": {
        "todo-tree.regex.regex": "((>| |@)\\s*($TAGS)\\{*|^\\s*- \\[ \\])",
        "todo-tree.regex.regexCaseSensitive": false,
        // other
        "editor.defaultFormatter": "nickfode.latex-formatter"
    },

    "todo-tree.regex.regex": "((>| |@)\\s*($TAGS)\\{*|^\\s*- \\[ \\])",
    "[latex]": {
        "todo-tree.regex.regexCaseSensitive": false,
        // other
        "editor.defaultFormatter": "nickfode.latex-formatter"
    },

I verified that I am using the right language id :
