hide Post Author badge in comments

Classical Theme seems to create a blue “Post Author” in comment. I found this, but solutions don’t seem to work:

I also tried this…

.comment-meta cite.fn {
display:    none; !important;
}

…but it also hides the Author’s name (which I don’t want).

Any suggestions on how to just hide the “Post Author” badge in the comments?

Thanks for any help
