USBC ports not working

2017 Macbook Pro

I am having an issue. My LEFT USB-C Ports are not working when I plug any devices in (Monitor, USB Drive or iPhone)

However, if I plug in my USB-C Power supply to the left side USBC ports, it works.

I have tried the following:

1. Reset SMC
2. Reset PRAM/NVRAM
3. Ran Diagnostic Check (came back with no issues)
4. Booted in Safe Mode to see if it was a software issue.

I also noticed, if I plug my USBC power adapter in the right side, it goes in AC Power only for about a few seconds, then begins to charge.

What could the issue be? It didn't show anything for logic board when I did diagnostic testing so I am a bit confused?
