Unique Indexes Creating Themselves...?

Hello! When I create a new feature class in SDE (v10, SQL Server), it automatically gives itself a unique index (see attached). The documentation on the topic doesn't help; it states that unique indexes aren't even possible on SQL Server SDE, which evidently is incorrect. This appears to be a new problem, but I am stumped as to what created it.  How is this happening? Thanks!
