I think I updated the plugin and after that activated, but it could also be that I activated the plugin and then updated (don't know if it matters). I think I acually used the Updater plugin (which normally works without problem). Then I navigated to the Site tab and I saw some weird markings on the right instead of the list of settings. So I dissabled plugin GS Config UI and all settings are gone.
I think GS Custom Settings stores all settings in /data/other/custom_settings/data.json . That files is now completely empty.
I guess I have to test this better..
