I trying to create my set of brushes. It creates but i found really buggy this point - custom curves for controllers. It not hold/save it. When i reopen Affinity Photo - the brushes preview is looks weird (until i adjust it again) and my custom adjusted curve for controller is resets to defaults. How i can keep it saved? After custom curve created i want to use it in other controllers too. Is this bug or feature?
