WordPress parent page title in admin page listing

I recently noticed that I can’t see parent page name in the admin area where you can see pages. I started digging why is that and noticed that in the file
wp-admin/includes/class-wp-posts-list-table.php row 726 there is a method called column_title where there is an if statement like:
if ( 0 === $this->current_level && (int) $post->post_parent > 0 ) {

So I understand that when current level is 0 it enters into the statement and gives $parent_name a value. As I understand this current_level should be something else rather than 0.

Can somebody tell me is it a bug, feature or a setting which is turned off somewhere?

The result I want to achieve is that I want it to show the parent page name in the admin page listing environment. (Illustrative image of the wanted end result https://qsnapnet.com/snaps/fv810hibzrxjemi )

Thanks in advance.
