nav menus does not show custom post type options

[caiovncius]

i installing wordpress in localhost, for plugins development.
But i installing woocommerce and in my plugin i using custom post types.

In nav menus, not show custom post types options for create itens in menu.

I create a new custom post type, for tests, in functions.php in my theme, but not success.

i used all arguments of register post types and taxonomy, but not working.

1. Could you provide your post type registration code?
2. Make sure the post types are not hidden in screen options (in the upper right corner).

I see Courses, Enrolls, and Classes, as well as Course Categories with your code: 29301.png​.

Make sure they're not hidden in screen options on your install.
