How to hide children categories

When using Menu > GMap > Blog list .. I get children categories shown at the bottom.
How to disable those?

The blog list is a parent category consisting of 2 childs.

PS: Where in documenation do I find "Personalization" and how to use that?

Hi,
Not sure where to look for version number.
However, in extensions it says: Package 4.0.17

Probably latest version as I downloaded it recently.

PHP 8.2.24
Joomla 5.2.2

Hi again
I want to show the listing in the child categories, but not the related categories.

Explanation:
Category: Anchestors
Sub-category 1: My dads family
Sub-category 2: My moms family

The created items in each category should be listed, but I don't want the category description shown. Even if I set "Category title" and "Category description" to "Hide" in the menu, I still get those listed (see image).

On Personalization: How does that work? How do I relate a personalization to the map at all?

PS: A workaround to hide the subcategories is by using custom-css, but that is really strange if needed:

div.cat-children h3
{
display:none;
}
