Hello,
I have K2 category structure as below:

root > cat1 > cat2 > cat3 > cat4

And I would like to list links from cat4 category by the K2 tools module.

It is not possible even though when I double checked that there are articles in this category.
Levels to render is set to 99. I am using Additional categories.

WHat is strange, when I changed category to my root category and cat1 module worked properly.
