I have a p5 panel that is 4 wide X 5 high and I have been able to get it going, BUT the screen is duplicated with the image appearing on the 2 panels on left hand side of the panel and then again on the 2 panels on the right hand side. It is as if it is outputting to two 2x5 panels side by side with the same image appearing on each half. I cant seem to find how to fix this and have played around with the nodes and strings and the direction, but nothing seems to work.

I am going from Xlights to a FPP and then a colourlight card. I have tested the colorlight card through Ledvision and it works a treat there with the image appearing as it should across the whole panel.

On initial review you fpp is looking form the font for your connections and the 0,0 starting is the upper left, not upper right. If yo turn on the test pattern from the panel screen what does it look like? Is it possible to get pictures of the physical back of the matrix, and also images of how it displays normally and with the test pattern? Out of curiosity what version of FPP are you using and what version of firmware is on the colorlight card.
