As per the title ive been experiencing duplicate cabinets again, a version that is usable and a version that is broken down into single components not grouped and doesnt update and requires deleting. 

I'm also getting this sort of thing happening with a geometry appearing and out of position. This particular screenshot one is happening to the upstand which is clearly at the back of the unit but there is also a rectangle at the front. Ive also had it happen on door rails.
