Check your LEDs to make sure that they are all facing the same direction. It is likely that D13 is backwards.
Once you fix that, check to see which LEDs are lit when D12 is supposed to be on. Check carefully to see if there are any solder joints that are not solid, at *any* of those LEDs that you’ve listed. Also check to be sure that there are not any unintended connections between the LEDs, or (for example) the resistors that lead to them.
