Command "Export the names of list of wires" exports duplicates

Hi,

Whenever I try using command ""Export the names of list of wires" it exports duplicates of names. For e.g. I have a name conductor named "16AWG" and when I use this command it exports two of the same so:
"16AWG"
"16AWG"

Please see attached file.

Is there a way to fix this?

Thank you in advance!
