Get redirected to wrong page when trying to register

I have buddy press and WPMU membership plugin installed.

I have created a register page with the [subscriptionform] code added.

The buddypress and the membership register page is set to the page where the form is added.

But when I try to register I get redirected to the registration cancelled page.

When I just type the page URL in the address (ex. http://www.domain.com/registration) I get redirected to the home page.
