Multiple lines of data on "Extra Information"

Summary

Pulling data from extra information, appears to produce duplicate lines when changes are made

Hi

I'm trying to build a report using the Personal / Extra Information fields; where it is recorded if employee has a disability or is a member of a minority group.  In instances where a "Y" value is recorded, it appears the report is returning 2 lines of data, one for the initial "N" on record and one for the "Y" update.  Is there a way I can get the "Y" to over-ride the "N?

Thanks
