Import Of IntelliJ IDEA Code Style XML File Does Not Change Properties Of IntelliJ IDEA Code Styles

EDIT: sorry! i didn't google enough: https://intellij-support.jetbrains.com/hc/en-us/community/posts/207329585-Code-style-configuration-in-config-codestyles-not-working

the problem is, that the file is obsolete. i used the file from this pull request which worked like a charm: https://github.com/bundeskanzler4711/styleguide/blob/11af152db373e565de1006f13944d3e07a75c8d7/intellij-google-style.xml

Hey girls und guys!

I am having the strange problem, that importing and using of a Code Style does not effect the properties at all. There won't be any changes to them.

I am importing this file found on github: https://github.com/google/styleguide/blob/gh-pages/intellij-java-google-style.xml

After importing, the properties remain the same. I tried to press apply, restart IntelliJ IDEA, copying the imported code style to the project. Nothing changes.

On the screenshot below you can see that INDENT_SIZE is 2, for example. In the preferences window is still shows 4.

Is the file too old? Were there changes? Is this a potential bug? I googled and found nothing on that topic.
