Hi Shane,
the problem is that the register-four view shows the products and if you create child experiences, all the child posts on the view. The idea on the view (single-boat-view) is to show only the product created by the author and not the product and the child posts.
Is there any custom coding on this site at all that is meant to target the view ? Your view is in fact listing out post from the experiences CPT as well.
The only custom code is kept in the GeneratePress Extender plugin - see GP Extender plugin on the dashboard menu in the backend. Nothing obvious stands out though. I have set up a relationship between the Products and Experiences in Toolset (one to many) but I thought that sat independently of this view.
You are welcome to deactivate any plugins if that helps - I've tried that but it didn't change anything.
