Downloaded SP 1.0 yesterday and started using it today. Found a major issue with regards to labels. Below, see a standard bottle model with a cap. As you can see, listed under "B-97632_2_Render-1", there is a single color listed. This is the normal behavior.
Below, you can see what happens with the same model is imported with labels. A plethora of colors listed. When I try to add my appearance, only a single face is selected, instead of the entire part. I hope this is not working as intended.
