Hi,
Your categories listing module is not a HikaShop module. It's a third party extension.
So maybe there is a problem with it ? Are the categories properly displayed if you use a HikaShop content module like the "categories on 2 levels" one which is preinstalled by default ?
If yes, then the problem in is the module, if not, then the problem is in the categories themselves.
As I said, check that they are enabled.
Also, they might not be displayed because they don't have any products, or you have configured them to be displayed only for some user groups.
Finally, you can try to click on the "rebuild" button of the categories listing, it might help.
