BuddyPress.org

I am using the latest version of buddypress and wordpress and everything seems to be running except for one thing. Most of my users were able to register without a problem except for a few have let me know that they received a different activation email.

Most of the users receive the regular email with a link to confirm their registration to my site but the other users get that same email except they are redirected to a page that is asking for an activation key instead of being confirmed automatically.

Is this a bug? Is there something I can do to make this stop? I would appreciate any help with this.

Thanks
