LetsEncrypt SSL shown instead of Cloudflare SSL

I had let’s encrypt free 3 month SSL on my website digitalcolumns.com. Today I installed Cloudflare SSL. But even after installing Cloudflare SSL still, old Let’s encrypt SSL is shown in the browser whereas in SSL Labs Cloudflare is shown. Please help me with this issue.
