Primary Navigation disappeared

Hello! I’ve had this installed for many months now with no issues. However, I’ve noticed recently (probably after a recent update of the plugin and/or Genesis) that on any page/post where I have a secondary menu enabled, the primary menu has disappeared. All of these have “Default” selected as the primary menu option, but it seems that no longer works… I have to go into every post to manually select the Primary Menu, and then it shows up. Is there a way to fix it so that a default menu still shows up without having to manually select it on each post?
