IntelliJ keeps resetting right margin go 100 characters

Hi,

I need right margin to be 80 characters. Every time I restart IntelliJ, it resets this setting back to 100. The setting is "Right margin (columns)" under "Code Style".

How can I make IntelliJ remember this setting through restarts?

Thanks!

EDIT: found it myself, there was a "Scheme" selected at the top of the settings, I have overridden it with my own and now it seems to remember it
