Am | the only person who thinks this is a bug? If you select one or two subcategories or sub-subcategories whilst editing a post, it's clear from the category hierarchy that you can see which subcategories you've selected.
However, when going in to re-edit or update a post, all the categories or subcategories you have selected have been moved in the sidebar to the top of the 'categories'
e.g.
Categories
Cheese
-- French
-- German
-- Greek
-- English
Meat
-- French
-- German
-- Greek
-- English
Then if the post is 'in' the categories
- Cheese > French
AND - Meat > French
The category 'sidebar' in the post editor shows the VERY confusing
French
French
Cheese
-- German
-- Greek
-- English
Meat
-- German
-- Greek
-- English
If You have the following sort of subcategory structure, it's a NIGHTMARE but I can't see a way round this. AMazed that I can't find anything on this annoyance in the Codex or support... but happy for you to prove me wrong...
