Custom Registration Fields

Hi, we have several custom registration fields for members to fill in. However, in the dashboard of the new Responsive Directory Theme, under ‘General Setup’ > ‘Registration’ where we have added new fields, two of them named ‘On Behalf of’ are malfunctioning. We cannot delete nor edit either field. If we click on delete, the last field added will be removed, but not the one we have clicked on. Any advice for fixing this issue? This is important to us as members are now signing up to our site and this needs to be fixed pronto. So any and all help is much appreciated!!

Kind regards,
Jon
