Anil,
Are you registering with the 'Register' button or link to create a Joomla user or are you registering with a social network?
If it's a Joomla user, then SCLogin is only redirecting to whatever component is set up in the 'Registration Component' option. We have no control over what happens when you use create the Joomla user this way. If you are using a third-party extension, you will need to contact those extension developers to resolve the issue.
If you're registering via a social network, then we will need more details such as what Social Profiles you have enabled, is Automatic Registration enabled, what fields are showing on the login/register page, etc before we can help narrow down the issue.
