To overlay a component, look at Client-side Customizaton and the Overlay tutorial.
If you overlay reviews by copying to /apps/social/reviews/components/hbs/reviews (same path as /libs, but in /apps instead), then you do not need to go into design mode and change the resource type.
Relative resources are first looked for in /apps, and if not found, are looked for in /libs. Thus, when customizing a resource, you can leave most of the functionality in /libs and only copy customized resources into apps.
The only time you might go into design mode to edit the component's resourceType is when a new extended component has been created and you want to switch an existing placed component to the newly customized one. And, as described in the Changing to a Custom Review Type section, it is suggested to still use relative paths (do not include either "/libs/" or "/apps/").
Since your screenshot suggests an overlay, I would guess your problem might be that you need to use CRX|DE lite to modify the properties of /apps/social/reviews/components/hbs/reviews and /apps/social/reviews/components/hbs/reviews/review in a manner similar to the Overlay tutorial shown for the Comments component.
/apps/social/reviews/components/hbs/reviews
sling:resourceSuperType social/commons/components/hbs/comments
sling:resourceType social/reviews/components/hbs/reviews
/apps/social/reviews/components/hbs/reviews/review
sling:resourceSuperType social/commons/components/hbs/comments/comment
sling:resourceType social/reviews/components/hbs/reviews/review
I hope this helps.
