That's the key: qtlocation and qtspeech weren't  part of 6.2 qt5.git. So when switching from dev to 6.2.4, 'git checkout' leaves the submodules alone.

Haowei, you seem to have found the solution yourself previously: git clean -xfdf. Or just clone Qt 6.2.4 (and other branches/tags) in a separate git checkout directory.

But why do you want to build the documentation for Qt 6.2.4 yourself, in the first place? All the commits need to go into dev anyhow ...
