Subscription optimizing with buddypress

Hi

I am trying to set up the registration on my website, I am using buddypress and membership.
I saw that there is some conflict :
if I redirect to a specific page with membership people cannot subscribe because all the plugins (Buddypress Xprofile Custom Fields Type and Skt NURCaptcha) do not appear correctly.
So would there be a way that my subscribers register in 2 steps?
with different fields are each point,
or are there other ways?
the 2 pages are at the root
/register-3/
/register-4/

Thanks a lot

Best regards
