Dive Log

I was swimming in a pool and my MK2 logged it as a dive because I forgot to put the watch in pool mode. I was able to delete the dive on my iPhone in the app so that it did not throw off my number of logged dives. However I cannot delete the dive on the MK2. Does anyone know how to also delete the dive from the watch. I thought that deleting it in the App would remove it from the watch but it does not do that.
