I'm trying to set some Simple Sitemap settings programmatically. I'm using the following to set whether or not a specific node is indexed:

`\Drupal::service('simple_sitemap.generator')->setEntityInstanceSettings('node', $node->get('nid')->value, ['index' => FALSE]);`

This works fine and I was able to see the results reflected in my sitemap. However, this is only reflected in the "Simple Sitemap" form of that node if the value is set to `TRUE`. If `FALSE` neither radio button is selected. 

This is confusing to others who are editing the site. How can I get this reflected in the form?
