Unidentified field in registration process?

Hi SI Team,

Wishing you all an amazing 2017 & yes I have an issue.

If I go here:
http://www.finalbug.net/network-final-cut-pro-post-production-professionals/login-here
I see the following: “PLG_FIELDS_GEOCODER_INFO”
To me it looks like a broken/no longer used plugin.
I have searched the back end Joomla plugins for any thing map/geo related but am not finding anything.
Any ideas what this is or how I can get ride of this?

thanks in advance
Paul
