Duplicate Designer.vb file when saving dataset

I'm having the following problem. When I change the dataset in a project Visual Studio generates a duplicate designer.vb I've tried the solution that was suggested in a similar post of deleting the designer files and running the Custom Tool but I end up with 2 designer files again and of course all of the changes in the dataset are saved in the duplicate dataset1.designer.vb file instead of the correct one.
Of course, the project will not build unless you delete the dataset1.designer.vb file.

Any help would be appreciated.
