 Hello,

 I am seeing an issue with my site where the categories/subcategories tree
 isn't displaying correctly when editing a post. The categories are
 displaying and are setup correctly when viewing Posts > Categories. When
 editing a post, subcategories show up as main categories, rather than
 subcategories. This creates a big mess when working with many levels of
 subcategories.

 I have submitted a ticket to my host (WPEngine) about this problem. After
 further testing by their support engineers, they came to the conclusion
 that it is a WP bug. They found out that when the count row in the
 wp_term_taxonomy table is set to a 0 value, categories do not show up
 ordered correctly within the post. However, if the value is anything but
 0, it will show in all posts, be it that they exist or are newly created.

 Please advise on this issue.

 Thank you
