Problem with upgrade to v 4.2.1

After upgrade to version 4.2.1 — on home page of my site, under the main text but above comment boxes, there was a red RSS-feed icon displayed on the left side.

I see this in the changelog:
– Added the ability to show comments on home page

So I assume that’s the source of the problem.

However, I do NOT have comments enabled on my site — and I verified via the edit screen that comments are not enabled for that text block. I could not find any option within the customizer to toggle this new ability to display comments.

Source code showed this:

<div id="comments">

		
            <div class="row align-items-center mb-4">
                <div class="col-auto">

					
                </div><!-- .col-auto -->

				<div class="col-auto pl-sm-0"><a title="Follow replies" class="comment-feed" data-toggle="tooltip" data-placement="top" href="..../coming-soon/feed/"><svg class="icon icon-rss" aria-hidden="true" role="img"> <use xlink:href="..../wp/wp-content/themes/evolve/assets/images/icons.svg#icon-rss"></use> </svg></a></div>
            </div><!-- .row .align-items-center .mb-4 -->

		
    </div><!-- #comments -->

I was able to resolve the problem with display of the unwanted icon with this change to CSS:

.comment-feed {display:none;}

But of course I shouldn’t have to use CSS to clean up unwanted and unused elements on my site pages.
