I have set up a TEST project -with miles stone step-1, step-2, step-3 , step-4 .but I deleted step 5 and step 6 , When I have created new miles stone , it is starting fm step-7 and step 8 and not for step-5 and step-6 . How to correct it ? Can anyone come to join 30min call dedicated to understand JIRA project management settings ?
