Custom fields not showing on front-end data entry form

-- HikaShop version -- : 3.1.1
-- HikaMarket version -- : 1.7.3
-- Joomla version -- : 3.7
-- PHP version -- : 7
-- Browser(s) name and version -- : firefox

The custom fields are not showing up on the front-end data entry form. The display->custom fields->display front end is enabled. The data entry form shows when the menu item is clicked for a valid user. At the bottom of the form where the custom items should appear they do not appear. What am I missing.

The hikamarket setting is also set to show. font end editing. I have set this up before the updates and had no problems with the custom setting. Since your update custom setting do not always work like they should. So why is this not working? Please give me a useful answer.

I solved the problem. I had created the custom fields before I installed hikamarket. There are a couple of vendor variables added to the end of field after hikamarket is installed. Just was not aware of that.
