Categories not displayed on layered navigation

[Yohannento]

Hello,

I'am trying to display categories on layered navigation, I have read many posts about this problem but without success. All my categories are anchor but the categories are not displayed. I have created my own theme based on luma theme. 

I have tried this solution https://community.magento.com/t5/Magento-2-x-Programming/How-to-display-category-filter-on-layered-n... but it's not working. I'am under Magento 2.2.6

Is someone has an idea to resolve this issue ?
