Sidebars not working in Anew child theme

Hello! I installed the ANew theme (which is amazing, thank you Alexander) because I needed a theme that let me customize different sidebars for every page. The problem is that this doens’t work in the child theme. I’ll chose “right sidebar” as a layout on a single page but it keeps appearing on the left.

What can I do, please? Is there any other options instead of starting working with the parent theme again???

Thank you very much!
