Why can't I select and add a trade offer to the cart from the category page?

Question

Hello, I thought the problem was in the template, I downloaded the default template from the Emarket solution, the same thing.
Please tell me what could be the matter, why instead of choosing and clicking on the button in the basket I see a button for more details?
I turned on, turned off inventory control, manually indicated the quantity in stock, "Properties of offers added to the basket" - selected, I went through all the settings, nothing helps (On the page with the element, the selection works.
