Radio Fields Not Displaying Saved Value

Hello,

We are experiencing issues with radio fields that are required. When updating the value to 1 (yes in our case), and saving the custom post type record, the field displays the retained “Yes” value in the custom post type edit screen correctly.

But when we change it to a “No” (0) value and update the custom post type record, the field appears unset – http://screencast.com/t/btwyedaZEcO.

I checked directly in the database for the value of the field, and in both cases, Yes and No, the values are correct and updating in the database.

The issue is that when someone goes back into that CPT edit screen, it appears that the field is not set, and if we do not set it again, we get the validation message for a required field http://screencast.com/t/VpQpYynWJ (even though in the DB the value is actually set correctly at 0).

We are using WP 4.4.2 and the latest version of GD.

Thanks.
