User registration steps

Hello not sure which forum this belongs in.

i have the wordpress social login plugin working with my site. when a potential user clicks one of the social media icons to register, the user the clicks to allow access to the site. but then th next window that comes up again asks the user if the have an existing account or they are creating a new account. i find this step annoying because all users wil be new members and the wording on that page is confusing. i cannot find where to remove this second step.
help and thank you.
