Are you sure the Voulge was dropped in your nightmare game? Max sockets on a Voulge should be 4 starting with ilvl 26 and all area levels in nightmare are 36+. So it shouldn't be possible to get a Voulge in nightmare and then getting only 3 sockets from Larzuk.
Just to be clear it doesn't matter if you use Larzuk in normal, nightmare or hell. It only matters where you found the item you want to socket.
This is not a bug. A Voulge that drops in nightmare or hell will always roll 4 sockets from Larzuk (regardless of which difficulty the quest reward is used on), unless it dropped as low quality and was “repaired” to normal quality with the cube. If it dropped on normal difficulty it depends on the exact area it dropped.
