Hide Super User in K2 Article

I have disabled every show author, but it still shows super user at the bottom of the article.

i entered this in overrides..

.itemView .itemAuthorBlock,
.itemView .itemAuthorContent {
display:none;
}

It worked, but is there an option to just disable it?

Hi

It should be possible to disable it in K2 category settings or in menu item settings if more categories were attached to parent menu item.
