Hi @helvetica123,
Thank you for writing in,
It seems you have mixed up the Woocomerce and user registration, my account feature with the user registration. If you have registered the users from wooroccerce form then you can not edit the details using the user registration my account page because of the different fields.
On your my account page we suggest you replace the user registration my account page shortcode [user_registration_my_account]
then go to your dashboard >> user registration >> settings >> choose the same account page for your user registration plugin.
This will fix the user registration plugins register issues. If you would like to centralize all users to the same account page including already registered users using a different plugin then you can use the profile connect addon feature. Please check this documentation link for more details https://docs.wpeverest.com/user-registration/docs/user-registration-profile-connect/
Regards!
