Why is pro tools command-D duplicate feature such a piece of garbage still?

I had two clips which were perfectly trimmed to the grid which I then command-D duplicated about 10 times and it doesnt take long before they fall off the grid. I've seen this issue on multiple versions of pro tools at this point. How is this still something they can't fix?
