Thanks for reaching out.
I'm not sure if I understand the issue correctly, would you mind clarifying what's the content area? Is it the builder's content area like this?
If yes, then I can't confirm the issue. All I can see from your site is you only have one blog post so it's only normal to see the pages, mostly.
And if you haven't allowed or permitted post editing yet, then please go to Admin > X or Pro > Settings > Permissions and make sure Post is allowed.
Then test it again, else, please provide your admin login credentials in the secure note so we could confirm the issue you're getting. And yes, please increase execution time and memory limit to make sure it's not related to it.
