Benito,
You need to change the dependencies settings from "Latest" to "As Stored". I am on Windchill 10.1, so hopefully the screenshot makes some sense.
Click on the Edit Dependencies Icon and choose As Stored. In the dialog box that appears, I think you should be able to just click on the OK button.
Once you do that, just visually check to see if your dependencies have changed from Latest to As Stored.
Oh, and before you start, make sure your workspace doesn't have any later versions of the objects.
