Change "Reply" text on comment

Good Day,

I'm having a problem where commenters just dump a new comment as a reply to the last comment in line under a post, rather than using the comment form at the top of the comments to start a new thread. About half my users are doing this!

I would like to change the text of the reply to a comment link to something like "Reply to COMMENT ABOVE".

I tried doing that in the settings/phrases/Reply to but that did not change it.

I then tried this filter to add to the text and that did nothing.

add_filter("wpdiscuz_after_reply_button", function ($html, $comment, $user, $currentUser) {
    $html .= "To COMMENT ABOVE";
    return $html;
}, 10, 4);

Any idea how I can fix this problem? 

The example link above has short comment threads, but this is a real problem on some of my Pay walled chapters with a lot of comments.
