Hi again,

You don’t need to overwrite all the css and js from the main theme, this is not necessary.
Just add custom css to the style.css file: https://ibb.co/68qhJrh

I have just fixed all issues, please delete all caches and recheck.

All the customizations I have added to the style.css file (child-theme) for you, when you update the main theme this custom css will not be lost.
