Zip Code field invisible in Membership [subscriptionform]

I am using Membership for the [subscriptionform] on my registration page. Another question I asked here suggested I use BuddyPress to get extended profiles.
That works EXCEPT now the zip code field is inaccessible to new users who are registering. If I link Buddypress to my registration page it removes customer content and my widgets like it's overriding the actual page settings.
