users not put into default membership


i am trying to make a simple site:

users sign in / register with social login
can see all the buddypress stuff but not coursepress

i have made two memberships for annual and monthly payments which allow them to access the courses.

i have made a default membership

however when i test this by signing them in it seems like they are listed as "visitors" and not added to the default membership. this means they cannot create groups.

thanks for any help!

ill provide access now
