Failed to start circlet - there are unknown feature flags in configuration file: [NEW_DASHBOARD_LAYOUT, RECONNECT_ONLY_LIVE_ARENAS, SINGLE_PROJECT_NAVIGATION]

When I want to upgrad my space on premise installation to the current 2023.2.0 version I get following error, does anybody know why and how I can disable these unknown feature flags? Thanks!
