The issue occurs only in the "canvas input settings" column, other configurations are kept. If I alter the default profiles, the configuration keeps resetting itself on every startup. If I duplicate a default one, then configure it, the customized profile disappears after relaunches. This is my first time submitting a report and as a normal user I'm not sure if other information is necessary. Thanks for your efforts in advance.
