It was told on their website or app before that the first center chosen in the first gen election will center for a year till the next election happens. Sheki did post something on her social media account and apologize for being the center again but that post was taken down. Personally I also hope for a new center just like BNK did, but i just realized Melody from JKT48 also did center a lot of song before their first gen happens and no one complain about it. I think people start comparing MNL to BNK ways this days. I feel sorry for her even though she's not my fave member, she still deserve and work hard for it.
