You are right. Good Catch.
Prior to 4/20/2016 it was showing correctly (meaning …/2016/04/what-we-talk-about-when-we-talk-about.html) . There was probably an Nextscripts plugin update at that time which caused to get messed up. So after 4/21 all blogger links are messed up.

I really hope support can fix this quickly, as these links are bad for SEO

Thanks
