R4 allows for options to be given to the patient. If you open a course then without accepting the course open a new course. R4 allows you to go between the two courses to show the patient difference in cost, print different treatment plans etc. However when you accept one of the course, the other course is deleted. it does however stay inside your notes so you have proof that you gave the patient a choice.
From what you have written i believe this is what has happened.
Hope that helps
