I am having trouble with input text fields not being removed from a called scene when I exit (call previous) then scene to go back to the calling scene. I have tried removing all of the scene objects from the display group, using composer.removeScene, etc and no success.
This is the only screen so far with input the scenes above are all simple button selection. I have the code listing attached for the two scenes.
I know it has to be something simple because it always is, it is just hiding from me at this moment 
.
Any help will be appreciated.
