DDL for external table is not complete (4238505)

I have an external table for which I want to extract the DDL. If I extract in 6.3.1, I get the full external table DDL. If I extract it in 6.5, I only get the DDL as if it were an internal table. I've attempted to verify the settings are identical between the two versions, they are connecting to the same DB, and extracting DDL for the same external table. Am I missing something (entirely possible), or was this inadvertently broken in 6.5?

Also, possibly related, if I expand the table category in up the full DB navigator in 6.3.1, for this schema it behaves normally. If I expand the table category in DB Navigator in 6.5, it shows no tables despite the fact that the DB explorer shows 11 tables including two external tables.
