Chapter Marker end actions are OK if you can use a Chapter Playlist for the play all function. The only reason you couldn't use a chapter playlist when there are end actions on the chapter markers is if you need seamless playback and there aren't any natural breaks between chapters.
If that's the case, then you need to delete all of the chapter end actions and use a link to the timeline as your play all. Then for the scenes, you would create a chapter playlist for each individual chapter. Each chapter playlist would only contain the one chapter.
