Wrong Main Person

I don't have Geni pro, but the other day someone merged my some of my profiles which gave them a managed by "no name." I thought it would be beneficial to go in and fix the mess caused by this and someone else who was merging some of my profiles. I accidentally added the daughter of my cousin, but didn't realize she'd be a new profile manger for some of the profiles. So I want her not to manage those profiles. I also somehow screwed up and now my late Grandpa is the main profile for my Geni account. I want the default person to be me. I've tried creating a branch and merging those profiles, but that hasn't worked either. I could certainly use some help since I don't have Geni pro.
