Any help would be greatly appreciated.

Thanks for the clear photos. From what I can see, it looks like both of your leds are installed backwards.

LEDs are directional and if you put them in backwards they won't light up. To figure out which way is right, look on the PCB, at the image of the LED. One side of the image is slightly flattened. That indicates the negative side. The LEDs have one lead that is shorter than the other. The short lead is also negative

Hurm I followed the guide about longer leg being negative...it still isn't being detected in windows, the less being backwards shouldn't case that issue as we'll should itv

I can't see which leg was longer since they have been cut off. But the flattened side of the LEDs do not align with the diagram.
