Need to change the hook the plugin is using. It is currently using register_addmember_process, but should be using register_addmember_complete. What is happening is when it hits process, and say the user puts in the wrong captcha, doesn't match their passwords, doesn't put in a required field, etc. When you use the _complete hook it fires once the user has properly filled out the registration form. Only use this hook however if you want the registration to complete, but not get multiple notifications. If you are blocking registrations, then leave it using the process hook.
