gitk translate msg files not installed correctly

Hi all,
 I found a problem with the gitk translation msg file in windows, the
details are below:
1. The default gitk msg dir in windows is
[git_install_dir]\mingw64\share\gitk\lib\msgs, but the install process
does not install gitk msgs, no that dir exists
2. I use innoextract to unpack the git windows install
file(Git-2.33.0-64-bit.exe ), and I find that the gitk translate msg
files are not in the package ,is this correct?

So I think the gitk translation in windows does not work correctly, or
something i find is wrong?
