Android Studio 3.0 - Settings are not saved : <p>I've increased the "Right margin (columns)" in File->Settings->Editor->Code Style from default 100 to 140. Unfortunately the margin is reset after each time I restart Android Studio. I also tried to export and import my settings but this does not prevent the right margin to be reset.</p>

<p>Hopefully someone can tell me how to save the margin.</p>
