Hi: Would you mind looking at this post: Let $N$ be an abelian minimal normal subgroup of $G$. Then $N$ has a complement in $G$ iff $N\not\leq \Phi(G)$. In it not only the question but all three answers have zeroes on the left side. I find this weird. Any particular reason for it to have zeroes in all the windows?
There's nothing weird.
One person bothered to upvote the question, and one person bothered to downvote the question. These cancelled out to 0. Nobody bothered to vote any of the answers, so they are all scored 0 as well.
These things happen. If you want to do something about it, vote the competing answers (if they are helpful) or the question, if you haven't done that yet.
