Exporter exporting duplicate users

I've used Exporter to export all my AD users by selecting one DC.  For a few years the file is consistent in size and number of lines.    I upgraded to version 12.2.4 and suddenly the exports is over 60K lines instead of 18k.  I can see some users have 4 different lines even though all the info is the same.

Is there a setting I'm missing?  I'm wondering if its pulling in a separate line from all domain controllers?   I can't figure out what's changed, I'm using the same saved settings file I've always used.

Thanks in advance for any ideas
