Product pages not working correctly all of a sudden

Hello,

I have a question regarding the product pages suddenly not working correctly. The demo site link is:
https://www.texasleatherinteriors.com.php53-22.ord1-1.websitetestlink.com/

This issue I am having is for categories that have multiple pages loading all pages automatically rather than prompting the viewer to click on the next page when they are ready.

For example;
If you go to the living room tab in the navigation bar and then scroll down and click on Sofas and loveseats it will pull up all the products for that category, which is 209 and there are 32 items on each page. Then if you scroll to the bottom of the 1st page it immediately begins to load the items from page 2 and doesn’t give the option to go to page 2. It should not be doing this.

If the page is refreshed it corrects itself and the page #s show up listed at the bottom of the page and allows the viewer to click on page 2 where once on page 2 the issue repeats itself.

I checked the status of all my plugins, etc. and it is showing a visual composer that needs to be updated as well as the PHP has an update available. I have already contacted my host to address the PHP issues, but could either of these things be the cause of the issue or something entirely different?

Thank you for your advice on this!
