layered navigation: the category toolbar shows that incorrect counting and paging do not work

I have a problem with a live site where the toolbar shows the wrong product count, does not change the sorting address or the filter, nor does it change the product in the paging change.

You can see it here – Tuckers Butchers Poultry

Sample 1-33 of 33 products where the filter count is set to 20

If you click on page 2 at the bottom of the page, it changes to "21-53 of 33" but the products shown remain the same.

If you choose the "descending" price, again, the page is updated but the products remain the same.

I have a development site that runs the same code base that works well, both run Magento 2.3.3

The only difference is that the live site has docroot set up in / pub / and I was wondering if anyone else has seen this happen.

Interestingly, the toolbar works well in search results.

I would really appreciate your help.
