Over night, by CitizenPortraits folder are being deleted and duplicating

I create a new faction.  I load pictures to my CitizenPortraits folder, then in the game, I create a new species and a new civilization and all is good.   Then the next day, most all of my female photos are just about gone, and my male pics are duplicated and assigned has female.

This keep happening to all my created citizen portraits.
