change template positions

hi!

I want to change positions, top 6 and top 12

The problem is that I find the lines to modify positions, see if you can tell me:

I also need to change the position HEADER

thanks in advance

Hi, default layout structure you will find here: gk_esport\layouts\default.php
but also in this folder: gk_esport\layouts\blocks,
where we put "top" positions here: gk_esport\layouts\blocks\top.php
