Trying to submit soon but it now says my brother is a helper

[PoptartQueen]

So My name in minecraft is CayleeBug10 my nickname in creative is PoptartQueen basically I've been working on this one plot for one to two months (Mostly because I'm not on a lot but still) and my brother (Jaxson818, changes nicknames frequently) broke a block and replaced it. I was trying to submit my plot. I even broke and replaced the block but it's saying he's a helper still and I'm freaking out. Is there any way I can fix this? He's not even on the plot. I don't want him to be kicked like he's freaked out about but I need this to be fixed if someone can do it for me. Reguardless, Thanks.
