K2 Filter : error when hiding subcategories

Hello,

I've been trying to set up this module since yesterday and i'm having an hard time trying to hide the subcategories from the search results, not the items from the subcategories, but the subcategry blocks that shows in the search results.

When i uncheck "include sub-categories" i get this error :
1064
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ')' at line 1

Everythings fine when i activate it back.

Could you help me out ?

Thanks for your quick reply,

Im using joomla 3.10.2 with php 7.3.30 and i'm using your latest version of the module (just bought it a few days ago)

Okay so it's only about adding childrens item of subcategories in the results.
I have a K2 layout set up with subcategory blocks, but i want it to stay that way on this page.

If i understand it right i have to override the generic.php file if i want to have a different layout on the result than in the category view ?

No way to select another template than generic or the one already assigned to the category ?

Solved the problem creating a parent dummy category with a custom template and parameters restricting the module to this category and using the category template.

Thanks a lot for your help.
