Hi, for some reason the fields that are default in Joomla's user registration is also appearing in my form resulting in duplicates.
Is there a way to resolve this?
Try to disable k2 user profile from components-> k2-> configuration (or options)
Also, is there a way to integrate this with OSE Membership System?Sorry but we not have experience with OSE Membership System, anyway, Registration and Edit Profile page is the same of Joomla (tabs are generated by javascript), so if OSE Membership System have some User Plugin you will see this in these pages.
