blog entry no longer published after changes to Meta and Social are saved

Possible bug with Runway and blog.

A published blog article stops being published when changes are made and saved using the 'Meta and Social' tab of a blog entry.

In order to stop this happening I need to switch back to the first tab and press save a second time.

In summary, Need to press save on both tabs if updating the Meta data. Not the end of the world but it is annoying and potentially causes an issue for the client as it's easy to forget to do it.

Using Runway 3.0.11 with blog 5.6.1 installed.
