Hi,
I think here is another bug: I created the most simple one table design and a corresponding database scheme. So here is how it goes:
- load the design and click on right arrow ("Synchronize DD with model"), no differences!

- open the Browser and expand the relational model
- now click again on the right arrow ("Synchronize DD with model") and now the table is duplicated and another tablespace appears:

- the second table has a v1-variation in the name (storage details):

- repeat the steps and you get even more clones:

Best regards, Dieter
