Not recognizing custom taxonomies or post types.

I cant get the plugin to recognize the custom post type or taxonomies I have set up.

I have a custom post type called destinations with the taxonomies – activities , dates , locations and destinations.

The plugin is only giving me the option for the category taxonomy.

Does anyone know how I can fix this? Thank you in advance.
