booking only 3 Confirmed berths were available for the concerned journey leg or from Manmad to some station after Durg.
##
After 3 Confirmed berths were also exhausted, the status moved to the General Waitlist prevailing in this train (Usually Start-End)
##
For the Waitlisted Status, maximum booked was till WL 2 (Next passenger if booked would get WL 3)=> Thus status was showing WL 3.
##
However, due to cancellation the status had came down to RAC 17=> (Next passenger if booked would get RAC 18)=> Thus status was showing RAC 18.
##
Thus, the Waitlisted Passengers got their current (Booking) Status starting from RAC 18.
##
Since maximum RAC Limit defined for GN Quota against this train is RAC 18, the status again moved back to Waitlist (WL 1, WL 2).

The Current (Refreshed) Status you see is due to cancellations which has taken place after this ticket was booked)
