Error committing update set

I have 3 update sets in an instance. I've moved them all to another, the final, instance.

Now, I've commited the last one. When I checked the form in Agent Workspace I saw only half a form. I think it is because the rest of the form is in the other 2 update sets, which I haven't committed yet.

However, when I run a preview on one of them, I get an error: 

Found a local update that is newer than this one

What shall I do?
