Hi,

1. Ensure that you have the settings configured properly at EasySocial -> Settings -> Registration -> Quick Registration
2. Ensure that with the profile that you've set in the settings, go to EasySocial -> Profile Types -> Profile -> Custom Fields, and configure which fields should appear in quick registration by clicking on the field to load up the configuration panel.

If this is still not working for you, please provide your site's access so that we can investigate this issue.
