We recently upgraded a very old WordPress 5.x site to WordPress 6.1.1 and all seemed to go well but then it was reported that some taxonomies were generating new entries randomly.
So we have a taxonomy called article_type, which has entries like
- News - taxonomy=article_type & tag_ID=84 & post_type=post
- Opinion - taxonomy=article_type & tag_ID=90 & post_type=post
Suddenly all these new entries are starting to appear at the top of the list in edit-tags.php page, like this
- 431 - taxonomy=article_type & tag_ID=47033 & post_type=post
- 90 - taxonomy=article_type & tag_ID=47036 & post_type=post
So, the title in each new case is the ID of an existing entry.
The taxonomy is declared like this in code:
/* Article Type */ $labels = array( 'name' => _x( 'Article Type', 'taxonomy general name', 'sage' ), 'singular_name' => _x( 'Article Type', 'taxonomy singular name', 'sage' ), 'search_items' => __( 'Search Article Types', 'sage' ), 'all_items' => __( 'All Article Types', 'sage' ), 'parent_item' => __( 'Parent Article Type', 'sage' ), 'parent_item_colon' => __( 'Parent Article Type:', 'sage' ), 'edit_item' => __( 'Edit Article Type', 'sage' ), 'update_item' => __( 'Update Article Type', 'sage' ), 'add_new_item' => __( 'Add New Article Type', 'sage' ), 'new_item_name' => __( 'New Article Type Name', 'sage' ), 'menu_name' => __( 'Article Types', 'sage' ), ); $args = array( 'hierarchical' => false, 'labels' => $labels, 'public' => true, 'show_admin_column' => true, 'rewrite' => array( 'slug' => __( 'article-type', 'sage' ) ), ); register_taxonomy( 'article_type', array( 'post' ), $args );
I wonder if anyone has any ideas where to begin troubleshooting this?

So it seems when you edit/add a post and use a new article_type, like this:
Then this appears as a new numeric entry at the top of the article_type list. So it seems there's some code that's incorrectly grabbing/updating these and adding this in on a post update!
I have no idea where to even begin to look for this!

I wonder if this has anything to do with it? The only two taxonomies affected:
