Hello. Yes, the settings are saved when editing the category in the manager.
What that does not is show the images in the list of items into categories.
Only display 10 items in the list.
No shows pagination.
I had a template override, but I deleted, if it has not been something that I have not been disabled.

But I've watched almost all options and find nothing.
The template for K2 is the default.

Things I've tried.
I deleted the default k2 template and have gone up to the server from the installation files of k2, but no effect.

The pagination limit is determined by the sum of leading, primary, secondary items and links. A link to your site would be very helpful.

the sum of leading, primary, secondary items not saved either in the category.

When show items from a category in catItemBody, missing block itemImageBlock

Is this a link to a single category or to multiple categories? As i have told you again, if this is a menu link pointing to more than one categories then the settings can be found at the menu link edit page. So a screenshot of the menu settings would also be very helpful. If you do not have any overrides as you said the settings should work.

Add image

OK, since this is a menu link to a single category, the settings that are applied can be found at the category edit page. Take one screenshot from there also.

As you will see the category has a configuration that does not respect the frontend

You are editing a different category. The category of the link is named " Actualidad Bienestar Social" while i see a different name in the screenshots.

Bienestar Social category inherits parameter noticias- actualidad
