Check the Autonav settings by going into edit mode, choosing the Autonav block and selecting "Edit". For the drop down menu, "Sub-pages to display" should be set to "Display all" and "Sub-page levels" should be set to however many levels you need, or that the block is programmed to handle. You can choose "Display a custom amount" and put in the exact amount, like 2 or 3, or experiment to see how many levels are available. I browsed quickly through the docs and there were no specifics on the Autonav settings. You can also PM the theme developer if you have questions.
