I'm not so sure there's a bug here, necessarily. You didn't mention anything about due dates, only start dates. If there's no due date, the "due soon" filter shouldn't ever show the action in question.

Furthermore, what are the start dates we're talking about -- are they in the past, or the future? A "due soon" item won't show up in the menu bar/dock/sidebar counts or have the "due soon" styling if the start date for the item hasn't been reached yet, even if the due date for the item is within the "due soon" period set in Preferences. It will be caught by the "due soon" filter, however.
