Shipping options work selectively!!!

Two weeks ago, we created a new category of products, for which the Express delivery option does not appear in the cart. The issue applies only to the USA and the EU zones. For other geographic areas, all shipping methods are available. Interesting that when two products are added to the cart – one of the “problem category” and some other, the delivery options are loaded correctly. In the meantime, other products have been created, outside the problematic category, for which there is no problem with delivery option… At first glance it appears that the problem is either in the products themselves or in the category. But now, when trying to create a new product, even as a duplicate of an old one, which has no such issue, the problem is here again…
P.S Problem category (last added) is:
