I don't know if it's a bug but it will be helpfull.

My code:

$crud = new grocery_CRUD();

		$crud->set_relation('gallery_id', 'pages', 'title');

		$crud->change_field_type('gallery_id', 'readonly');

The output with this code will be the readonly gallery_id instead of pages.title.

I covered this, as well as included a work around here
