To resolve this, please do the following:
1. Edit the view. Make sure you can see the new values.
2. FINISH the view. (Next, next, finish.) This updates the views definition and references.
3. Test the Form, and the new values should appear in the forms context browser now, since this is pulled from the views definition (even if using form controls, or form rules etc. This still pulls from the view where the SMO is used).
