The correct behavior on startup is that D0, D1, D2, D3, and D4 should light up. So, it’s not that some of your LEDs are shifted, it’s just that one of them is not lighting up. Check the soldering at that LED location, and at the pins of the LED driver chips. Also make sure that that D1 is installed with the correct orientation.
