Sorry, I understand it.
It is because I added the following code in functions.php

function get_my_posts( $wp_query ) {
	global $current_user;
	if( is_admin() && !current_user_can('edit_others_posts')){
		$wp_query->set( 'author', $current_user->ID );
		$screen = get_current_screen();
	}
}
add_action('pre_get_posts', 'get_my_posts' );

I added “!wp_doing_ajax()” after is_admin().
It works fine. Thank you.
