Hi forum
Had an issue with a finished end, when I replaced a different finished end all the shelf holes only drilled on the original even though the shelf never changed. this seems wierd since I didn't change the shelf attributes just a left end.
If you go to the Cabinet Assembly Editor, and then go to the Shelf Partition Editor and delete the original shelf and add a new adjustable shelf the holes will show on the new end panel. Make note of the original spacing for the shelf that was in the original cabinet.
Try it and see if works for you.
