Multiple layer decals issue new Release 4.0.2

Our workflow uses dimension daily to show realistic mockups for labels applied to various formats. Usually we need to create multiple layers in the label with different kinds of materials for example to show gold foil details or glossy/matte finishes. To do this we apply the Decal and then duplicate it multiple times to simulate the various print layers. With the latest update we are no longer able to duplicate the decal applied to an object. Also, there are some issues with how the decal is rendered, at times there are white lines/breaks in the "label".  We have tried applying a second decal on the object and are able to, but we then need to align the two decals by eye and it is never perfectly aligned in the end. This is a huge issue for us as Dimension has been the best way to give realistic mockups to our clients with a good indication of the final effect when printed. This issue is an issue that the whole team is having on both mac and windows computers.
