Custom section in fileorder is not generated

[cschlosser]

There is also an issue with the file comments and my settings:

"doxdocgen.generic.briefTemplate": "<brief description>{text}",
"doxdocgen.generic.customTags": ["<detailed description>"],
"doxdocgen.generic.paramTemplate": "\\param[<in/out>] {param}{indent:32}<parameter description>",
"doxdocgen.generic.returnTemplate": "\\retval <value>{indent:32}<value description. Use \\return <descripton> when there are no specific values>",
"doxdocgen.c.commentPrefix": "//! ",
"doxdocgen.c.lastLine": "",
"doxdocgen.c.firstLine": "",
"doxdocgen.c.triggerSequence": "//!",
"doxdocgen.generic.order": [
    "brief",
    "empty",
    "custom",
    "empty",
    "tparam",
    "param",
    "empty",
    "return",
    "empty",
  ],
  // The order to use for the file comment. Values can be used multiple times. Valid values are shown in default setting.
"doxdocgen.file.fileTemplate": "\\file",
"doxdocgen.file.fileOrder": [
    "file",
    "brief",
    "empty",
    "custom"
],

This Results in:

The custom (aka detailed) line is missing.
