Not showing up on custom post type

I’ve got this running on a couple of sites. The plugin is configured to only display the share buttons (inline and fixed sidebar) on single post views for a few different post types.

It works perfectly on one site. Example links from a couple of post types:
https://b2b.kbb.com/news/view/kelley-blue-book-best-family-cars-of-2021/
https://b2b.kbb.com/pdfs/view/make-the-most-of-your-buying-signals-leads/

However on the other site, the buttons refuse to show up on the Blog custom post type that I have set up. The buttons do show up on News (which is just Posts renamed). Examples:
https://b2b.autotrader.com/news/view/autotrader-10-best-electric-cars-2021/
https://b2b.autotrader.com/blog/view/growing-your-fixed-ops-market-share/

It’s worth noting that all the code for these post types is practically identical across both sites, barring some superficial differences in the template.

I’ve cleared all caching, checked PHP error logs, checked the console for JS errors and searched for the elements in the inspector to make sure it wasn’t a CSS conflict. No issues with any of those things, so I’m at a loss.

I am using v1.1.15 of Social Snap Lite.
