IOS app scenes - not possible to quit without saving

I have a one scene with kodi inside. Afer saving it I have been force to edit this scne through scenes.yaml and rewrite a little bit. Everytime I try to look at this scene in IOS app and want to quit it aks quit without saving? Yes do nothing, NO do nothing too.
Because it is my one and only scene I do not know if manual edit is the problem, if kodi inside is problem or if every scene in mobile app do the same thing (not possible to quit without saving).
