Action count missing in lists other than Inbox, Waiting, Focus

The action section of the navigation bar in iOS has inbox, next, waiting, scheduled, someday, and your focus actions.

However, only inbox, waiting, and focus are showing the number of actions you have for that category.

I believe it is intentional. These three lists contains items that you should take care of at the first place. By contrast, Next list is a list of assorted items when it comes to priorities.

Yes, in other words it does not matter very much how many actions you have in Next, Someday, etc. On the other hand, you should keep your Inbox at near 0 and 20+ actions in Focus is a problem.
