I think we’re going round in circles.

“The topic “title” is showing, it is “support”

The topic title shows above the breadcrumb, and yours resolves as

<h1 class=”entry-title”>Support</h1>

On my site this title is the topic (entry) title. so for example my site at the same point as your support title shows

<h1 class=”entry-title”>Feeding Oats.</h1>

where the topic is “Feeding Oats”
”

Have you amended loop-single-reply?
