Old databases updated by DT Pro Office 2: How can I remove

When I opened a database in my DT Pro 2 I got a message asking if I wanted to update them. I selected yes. But then I noticed that I had two copies of the same database: the updated one and an empty one. Now I see that for one databases there are six versions: three in the open databasees, and three in the recent databases.
Two of them open the database, yet only the has the dtbase2 suffix.
