memnbership and pro sites

How can I enable membership plugin on the main site but still does not override the pro sites registration.

All I want to use the plugin for at this time is to hide content... that is it.

However, it totally took over the registration process. Can I disable that?

@KimberlyL @support replied here indicating to "Have you tried setting the Registration Page to None?"

This, I believe, was the settings but it still does not work.

Was the solution a suggestion or a actual solution? I seems that the membership plugin is really aggressive and takes over the registration process totally which blocks the pro sites registration from working.

The latest membership plugin and pro sites plugin is installed on the main site. This is the issue
