Any chance you have also set a due date on the containing project? That will override any due date on the actions (including no due date) when figuring out which group to use to display an action in the due view. If you've got an action marked due July 6, but the project is marked due July 1, that action will turn up in the Due Yesterday group on July 2.

As for items in the Inbox not appearing, they only show up in Project mode views where the Inbox has been selected in the sidebar. It has behaved this way for as long as I can remember, and my primary suggestion would be to immediately file any Inbox material that has a due date. If you turn on the Show Due Soon indicators (Data pane of the preferences) you will get a red number appearing next to the Inbox in the sidebar to show that there are overdue items, or an orange number if there are no overdue items but some items due within the "due soon" interval (set in the same place). If there aren't any items in those two categories, you'll get a gray number which is a count of the items in the Inbox.
