Facebook Links Not Appearing

The links on my site are not showing up on Facebook, either through sharing it using the Jetpack extension or just copy and pasting the link directly.

The same thing happened to a different post of mine until I edited the permalink to appear into:

I’m not really sure what is going on but this has happened for a few of the posts and is generally inconsistent. Is this a bug with wordpress or jetpack? I’m not really sure what is going on.
