If you are tunning your model, or need to run the analysis with a more recent model version, you can overwrite this behaviour in the application settings window, enabling Force model in deliveries checkbox.
When you create an Application, by default, Force Model in deliveries is not enabled.
If you create Kiuwan applications programatically (i.e. not using web interface), you can set this option also programatically.
Please visit Kiuwan Local Analyzer CLI - Command Line Interface for help on how to do it.
