Hi Minh Nguyen, 
For this edit, my intention was to ensure that the crossing tag values are consistent between the node and way representing the same crossing. Unfortunately I did not have access ground imagery sources to verify the presence of traffic signals, so I chose to use the crossing=marked value from the way https://www.openstreetmap.org/way/1118165359 since the markings are visible in aerial imagery. I apologize if this caused issues. You are welcome to make adjustments, or if you can provide an imagery source where those signals are visible, I can make an update.  
Thanks, VLD288
