Routing issue

I have a listing website as INPUT and enqueueLinksenqueueLinks of it. These links (case studies) at the time has also multiple pages. When the cralwer adds the links with the new label attached, it's not happening anything. When using only case study page, it's scrapping the data and working. Not sure, what to do next and how to test it more. Does the Queue System waits to complete to add all links to start scrapping?
