Trouble with pixel order, Falcon F16v3

I set up a row of five arches made with 2812b strips. The arches are 90 pixels each with the exception of the last one, which is 88 pixels. I am running an F16v3 and Raspberry Pi with xLights. This is my experimental setup as I am new and learning everything.
All is well with getting everything to light, but despite the fact that I am plugged into five ports, data is being sent over six ports. I determined this by using the test mode for the Falcon controller and enabling individual ports. This is the number of pixels being lit by each port:
P1- 60 pixels
P2- 70 pixels
P3- 100 pixels
P4- 90 pixels
P5- 90 pixels
P6- 38 pixels
What I am trying to convey is that port 1 lights up 60 pixels on arch one, port 2 lights up the remaining thirty pixels of arch one and the first 40 of arch two and so on down the line.
I can create file in xLights, but they do not work in accordance with what I programmed. I thought I could work this out but it is about to make me pull out what little hair I have left. Any help is appreciated.

On a side note, I tried to post this on the Falcon Christmas forum, but the Recaptcha system keeps rejecting the post. One Recaptcha level is frustrating, three is insanity.
 
Sounds like a pixel controller string configuration issue.

Have you defined the pixel counts per output for the controller via the Falcon web interface?

Maybe post a screen shot of your controller configuration
 
Looks to me like you have overlapping channels. Port 2 should have start channel 271, port 3 start channel 541, port 4 start channel 811, port 5 start channel 1081 and port 6 start channel 1351. Each pixel is 3 channel therefore each port of 90 pixels is 270 channels each.
 
Dan,
That seems to have resolved the problem. I cloned strings so that all 16 ports are the same and the lights are showing the xLights sequences that I input.
I should have seen this but there are a lot of pages with a lot of input to cover, especially when starting out.
Thanks for pointing out what should have been obvious; I was ready to put everything up for sale I was so frustrated!
