Import of DDL with Foreign Keys Fails.

Using Teiid Designer 7.7 plugin into Eclipse 3.7.2, After importing DDL into relational source model, Foreign Keys are all renamed as FK_1 and then flagged with duplicate name errors. I am able to redo the Foreign Keys manually in desigenr but needless to say this is cumbersome. Are there any other workarounds to this problem. Attached is the DDL.
