When BOTH are illuminated it produces the Yellow.
Each color group (red,green) has a separate output port on the driver chip, a separate switching transistor, and separate biasing resistor. So assuming there is not a connector issue, which seems implausible since you are getting some illumination on each side, it comes down to the items in the above sentence.
Maybe this can help you deduce the the problem as it is difficult without seeing it first-hand.
Found out my issue, I had swapped my shell at the same time and apparently after troubleshooting a bit I found out the the last LED on the chain is pressure sensitive and I did not have the screw tight enough to press the right amount on that LED. If you press on it lightly all 3 leds will only blink red. Pressing on it harder yields all colors. Call it weird but I examined it for a while before forming the conclusion and tightening it down a bit more. All is well now and a few more flights in on 3.12.
You have a fault. Loose solder joint(s), damaged runner(s), etc.
There is no need for external pressure to make an electrical connection on the ESC PCB for the LEDs.
