From the Abyss of Dagath: Update 34 patch notes:

Additionally, players who already own Flawed Mods have had them replaced with the normal variant with this update's release -- excluding the April Fool’s Flawed Ammo Drum from 2016, of course. The conversion maintained the Mod rank, so a Rank 3 Flawed Vitality has become a Rank 3 Vitality, etc.
