Wonder if someone was in the wiring harness doing a repair, and when putting it together, and mixed wire colors, ie color blind.
If everything else is correct, I would be tempered to snip wires on that light near the socket and switch them , and if it works , just tape it up, use solder, shrink tube and good tape, or water proof connectors.
I presume you have pulled the bulbs and checked the sockets make sure the connectors look good,
I think mine are LED, but not 100% sure on that , never had them out (2014 sport)
Now I am going to have a look , back up is likely just regular bulb.
