Good Evening!
Please accept my apologies.
The language barrier doesn't let me find out the menu item that is assigned to the page in question. Yes, I could gave you custom CSS to eliminate those blocks but I wanted to check if the menu item has the control there, as it supposed to have some.
But I can not login to your admin area anymore.
However, here is the code snippet that you can add to your custom CSS:
.com-content.view-article #sp-main-body .article-details-intro {
display: none;
}
Kindly do let me know if it helps!
Best regards,
