All of the 'Anode' Pins (selectable 1.7 to 5.0 volts) are wired together on the LED64. This is the Red Wire.
The current is controlled on the cathode side of the LED; the black wire. So, you can't connect all the 'grounds' together in your project; but you can connect all the +5V together. We control the LED through the 'ground'.
