At removal or moving of posts to a basket, WordPress MU doesn't update the counter of posts in a blog. That пофиксить it is possible to add this problem in wp-includes/wpmu-defaul-filters.php lines:
add_action (‘ delete_post ’, ‘ update_posts_count ’);
add_action (‘ trash_post ’, ‘ update_posts_count ’);
If there is no desire to modify a code it is possible to create php a file in wp-content/mu-plugins and to add these lines there.
