When attempting to use this plugin, the custom courses interface removes access to standard post settings for other plugin's I have included in my wordpress site, and because of your custom editing interface, I have no way to set those values for these post types you are creating?
In nearly all other cases when I am on the content editing screen, I can see and set my other plugin's values. See the attached two examples of your custom editing environment, and the properties I am expecting to set from another custom types editing page.
Is there a setting I need to switch on somewhere in your plugin so these properties can be exposed? Otherwise, I won't be able to use this plugin because I have no way to define the settings.
