Your theme looks to be using post meta to display the sidebars, so there might be custom fields to configure which sidebar to display which will most likely be on the default WordPress post types (page and post) when you create/edit them. These options may not be on the bbPress post type creation/editing screens in the WordPress backend.

I see there is a ton of code that might not even be usable because bbPress post types may not have these custom field options to configure things like the slider, background color, and other options I can see in the code.

I do see from the classes that this uses a responsive grid layout so maybe focus and keep this class as it is a two column layout, one for the content and one for the sidebar.

You may need to contact your theme author for further help on this.
