For any cases with a PD of September 01, 2004 or later where the process completed after May 2012, the PD was never Current again until August 01, 2013.
Without the Conversion step, a visa could never have been requested under EB2 and the case would still show under EB3 in the Demand Data. When the case is approved, eventually the EB3 case will disappear from the EB3 Demand, although how long that takes is uncertain.
