Hi,
First try with the default template of Joomla as it might come from a customization of your template that the fields are not added.
Otherwise, please describe how you access that page ? Which menu item do you use and please provide a screenshot of the settings of the menu item.
Also, you can create a menu item of the type "HikaShop user control panel" and access the profile edition page from there (that's usually what people do). Normally, the fields should display there if the option is activated.
Finally, please provide a screenshot of some field that you're talking about ? So that we can see how you set it up.
