Neopixel blade build being troublesome.

[Wellthad]

I built my first hilt and decided to make my own led blade. The hilt went really well and works with other neopixel blades. But for some reason I can't get the one I built to function properly. It only lights up the first few leds and they are all white except for the last one lit is yellowish.

These are the leds I used. https://www.amazon.com/dp/B01CDTEHRC...ing=UTF8&psc=1

Things I've tried:
Replacing resistor
Swapping to larger Guage wire
Trimming from 144 leds down to 130 leds
I ordered a new pcb with the resistor already installed. I'm currently waiting on that.
