Display issues on single listing

I’ve tried to ask this before and was told it was a Genesis issue. But I’m pretty sure it’s not so I’ll try again.

We use Jetpack’s related posts on the news part of the site to deliver related articles at the end of each news story, and it does drive traffic round the site so we’re loathe to get rid of it.

There is code available to exclude the related posts from showing on any CPT, but it doesn’t seem to work for GD. So we thought we’d see what effect switching off related posts had on page views, but doing so wrecked all the single listings on GD.

It seems as if GD had a ‘snapshot’ of what to expect when it rendered a listing page, and the absence of the related listing threw all the footer up in to the middle of the listing. So we turned it back on.
We also see an additional ‘Title’ for related articles rendering on GD listings at the foot.

Oddly, this only happens on the profile tab, and related articles don’t appear if you view any of the other tabs, although the extra ‘related articles’ title does.

You can see this on any of the single listings, for example https://www.carsuk.net/places/united-kingdom/kent/east-peckham/car-service-repair/rcv-land-rover-specialists/.

We’ve tried all we can to resolve this, and have ensured WP Rocket is off and cleared when attempting to change it. But to no avail.

So if you have any ideas…
