Job title changes and 485 filing

My Perm was file as Software engineer 8 years back then I promoted as engineering manager and my H1b was adjusted to that. Few months back I am switch back to individual contributor with title as Sr software engineer in different department with different reporting manager. During all these position my job duties are not change for more than 50%. All position changes are with same employer. My Filing date is current now. Does my h1b title (manager engineering) and perm title (software engineer) needs to match? if yes Do we need to do this before we file 485? What are the complication I will face and what is best way to handle this?
