will the system correct episode numbers after deleting episodes?

I did some Test Runs on episodes to get familiar with how it works. I deleted these episodes. Then I scheduled two new episodes and it is still showing example: Episode 7, so I when changed it to Episode 3. Will I need to do this everytime or will the system correct itself? If this does not make since to you please call me on Monday the 15th at 503-351-6078 and I am on Pacific Time. Thanks - Cindy
