IT looks like you table has duplicated data in it.
not all of the entries are identical, similar, but not identical. for example:
Brothman Beth Andover Borough 07821-4525 Sussex 3-24-12
Brothman Beth Andover Andover 07821-4525 Sussex 3-21-09
they look similar, but they are slightly different. it appears there are records in your Certified_Planning_Officials that have similar data in them
