Reverse cards should be there, though they may not be shown to you today. You should be able to see them in the browser (can be accessed from the Browse button).
Click the gears icon found besides the deck name on the main window, then Options and make sure the bury related new cards until the next day option is off.
If you want to study Front>Back and Back>Front cards together consistently, you can use the reposition option in the browser to change their order.
