Auction status in PON_AUCTION_HEADERS_ALL is showing active even for closed negotiation

Summary:

We have a requirement to fetch ACTIVE negotiations from Fusion for which we are using AUCTION_STATUS from PON_AUCTION_HEADERS_ALL. These active negotiations shouldn't be any other status other than ACTIVE like AMMENDED, CLOSED, COMPLETED etc. But the column AUCTION_STATUS is showing ACTIVE even for closed and amended negotiations. Is there any other column or group of columns that we can utilize to directly fetch all ACTIVE negotiations ?
