Addding a Chapter to existing scene selection in DVD Arch
 

I forgot to add a chapter point so that my last scene of the selection menu won't run the films credits. I have added the chapter point between the last scene and the credits after the fact, but DVD Arch doesn't reconginze the last chapter point, I re-inserted a scene selection, added the credits chapter marker and then removed the credits button, but still the scene before will run thru the credits. I have run out of ideas, can anybody tell what I need to do or what I am doing wrong. Can I add a chapter to an existing scene selection without having to have a button on the menu. Thanks for any help on this one.
