Hi,
Edit the module via the joomla modules manager and go in the HikaShop options tab. There, you'll see all the settings to configure the display of the products.
Among them, you'll have the "ordering column" and "ordering direction" settings which allows you to select on which field the ordering of the products will be based and the direction of the ordering.
Other settings can potentially influentiate that too like the "random" option which can make the products displayed randomly ordered.
If you want to learn more about menu and modules display of HikaShop categories and products you can read more about all that here:
