Well, that seems correct too.
If it’s not the resistors, then it must be the LEDs, or the connections between them.
You might further check all permutations, and make sure that there are no other odd connections between the LEDx lines.
However, I would say that one possible case is that there is an issue with those three blue LEDs. Have you done any resoldering work or relalignment on those since it was working?
