I think that the denied CC's screen is made to bring to attention about automatic transactions that were declined, whereas manual declines doesn't need to.
Even more, sometimes it bothers me to have manual declines listed there. I think that they have to try to be recharged. I had a parent that gave me a cc to try but got declined, so ha gave me a different cc which was processed, but since I saw the declined charge on the screen I kept recharging and calling him that his charge keeps getting declined, so long when actually his different cc kept getting processed.
