The capacity stated now may be the capacity rated to maximum lift height as opposed to what was there before.
It may have showed capacity from the floor up to 89" or some other height than showed a reduced capacity for anything higher.
I have encountered this when some dealers supply new capacity plates. You can fill every form out exactly as instructed to a T and they will still find a way to f.... it up. I often wonder if there own technicians go through this. I suspect no.
