Date showing in Analyzer as number

After upgrading to NW04S, SP9, key figure with type DAT (Date field yyyymmdd) is showing up in NW04S Analyzer as a number instead of as a date. Instead of showing 12/1/2006, it is showing 39,052.

In RSRT, the same query shows the correct date of 12/1/2006 for this key figure but in Analyzer it isn't. Any ideas on fix to this? Thanks for your help.
