Change register link in membership2 pro

Hi there,

I've been having issues with member registration and have realised its because users have found an alternative way of registering via the 'register' link found at the bottom of all login forms and account pages.

I need to change this link to point to my specific membership page instead so how do I do that?

I've chosen the correct page in settings>general> registration but the link is still pointing to this auto linked page:
https://mywebsite/memberships/?step=register

Can you help? Thanks,
