Those resistor values sound a bit high for 5v. I have CC LEDs with the same basic specs, and I use 150,100,100 ohm resistors, I think they keep my LEDs under 20ma, or at least close to 20ma.
I have some SMT LEDs that are marked with the cathode mark, but they clearly work the opposite of the markings, so I can only assume its a manufacturing error, I didnt even know that you could buy parts that are mismarked, I just never heard of that happening.
Calcualting red for 2v@20ma with a 1k resistor, you will need to feed it 20 volts, i imagine at 5, it wouldnt even light up.
If you re-do your math, I think you will find that with 5v, all your resistors will be well under 200 ohms.
