Todoist Shows Incomplete Badge Icon In iOS even when no tasks due
My Todoist app icon on my iPad mini (iOS 7) almost always shows a red "1" badge for one due item when I have completed all my tasks for the day. If I launch Todoist it will show me that there are no tasks due but when I exit the badge persists. I've tried refreshing multiple times and checking Todoist from multiple other apps (Android and Mac OS X) to make sure there are no tasks left undone that aren't showing up in my iPad app, but have found nothing. Occasionally, if I complete my last task for the day with my iPad app, the badge will clear briefly, but later it will almost always be back.
On a side note, a feature suggestion I have is to offer iOS and Android users the option of showing a green check mark badge on their app icon when they're clear for the day.
