Hi,
Do you mean that you opened Aqua Mail's general Settings -> Smart Folder -> Smart Folder time period -> One day? In addition once you are there check how you've set the "Default sort order" function - Unread first, Starred first, data/time, etc.
In addition if you are unable to still set this up, please contact us with a screenshot, the application and Android version at support@aqual-mail.com.
