When I click on that link it redirects to another post, perhaps you need to be logged-in to see it?
Perhaps it would be easiest if we had credentials to log in anyway to see what you have set up to understand why the sorting may not be working.
Let me mark your next reply as private so that we can get log-in credentials from you—you may want to create a temporary admin user for me to use that you can later delete. And be sure to have a current backup of your site.
I logged into your website to check this issue. You are currently using Beaver Builder to build this page, and including the view using a shortcode. hidden link
The view was created using the Blocks editor inside this page hidden link
And it seems that the view has some implementation issues.
Because you are using the Beaver Builder, I will suggest using the legacy editor to build the view instead of the blocks editor. I have already activated it in Toolset->Settings->General(tab)->Editing Experience.
You can read about the available shortcodes here https://toolset.com/documentation/programmer-reference/views/views-shortcodes/
I hope this helps. Let me know if you have any questions of if you still need assistance with this issue.
