Not Saving Description in WordPress 4.4

I can confirm the issue. Any plans to release an update?
Thanks!

I noticed this issue swell. Running 4.4 also!

I discovered that it’s actually not related to this plugin,
which in WordPress 4.4 won’t be any useful, since for any Custom Post Type
there is a new voice “All Posts” (or whatever name you chose for your CPT)
under the CPT panel in the Appearance > Menu page.

As I was saying, the bug is related to WordPress core:

For the moment, remove this line from nav-menu.php inside wp-includes:
