Config Not Working After 1.2.9 > 1.3.0 Upgrade

I ran into several issues after upgrading to v1.3.0 running on wordpress 4.4.1.

1) The author info is showing for my posts even though I have this disabled in the theme config.
2) I can’t add JavaScript in the custom HTML field for the header image. I see the text of the script rather than the script being executed.
3) Related posts are always displayed, even if I configure them not to display.
