Thousands of pagination files being crawled

Our site should only have about 400-450 pages. After looking through an SEOprofiler report of our site, I see we have thousands of pages in our news and blog area that look like the attached image.

They’re showing up as duplicate Titles in our site audit.

http://theplatform.com/about/news_and_events/p10/ shows the exact same content as http://theplatform.com/about/news_and_events/p10/p10/p10/

We’re getting a very similar situation with our blog and also seeing those show up in our duplicate content report. I can’t imagine any of this is good for our ranking on the SERP.

How can I fix this?
