Paweł,
Can you try to change values for the same properties but in Workspace Settings instead (CodeMix -> Workspace Settings)?
In general, a value customized in Workspace Settings overrides the one from User Settings. To simplify and remove possible confusion, we have decided to drop a direct support for User Settings in CodeMix, starting from today (we have just pushed an update).
Kind regards,
