Difference between bootstrap carousels and how to set up?
Do not use Views Bootstrap module. Rather just display the node (of type Carousel) full content.

Construct your view as follows:

Format: Unformatted list, show Content, Full Content

Filter Criteria: Content:type (= Carousel)

Pager: show 1 item only. 

Set jQuery update to 1.9 and load jquery-migrate

Your theme pulls Boostrap from CDN. Bootstrap Carousel requires another Bootstrap library in libraries folder. Is this optimal? I don't think so.
