Link gets cut off

When I paste the URL into the URL section of each portfolio item, my portfolio automatically clips the URL so then it doesn’t work.

For instance, the first item titled “Commission approves three oil…” should have the url

http://www.argusobserver.com/independent/news/commission-approves-three-oil-and-gas-bills/article_b8ab730e-9693-11e4-a147-97a23cce0a2e.html

But for some reason my portfolio clips it to

http://www.argusobserver.com/independent/news/commission-approves-three-oil-and-gas-bills/article_b8ab730e-9693-11e4-a147-97a23c/

So when people click “view more,” they are taken to a broken link.
