I know this issue was raised a few months ago. I'm not sure if Faithlife thinks that it has been corrected. But just in case...
Here's the URL in my address bar:
https://www.logos.com/products/search?view=list&start=&sort=newest&pageSize=60&unlocked=no
I'm seeing numerous items in the product list which correctly have the "Add to cart" button grayed out but shouldn't be in the list at all.
FYI...
