NEW to Xlights - Trying to setup a 7x21 matrix

[Babalo09]

I am using an alphaPix4 controller and am tring to setup a 7x21 matrix. Right now it is all jumbled. There are 1 strand off 100 on output 3 and 1 strand of 47 on output4. The lights run from the bottom right horizontally back and forth.

Controller setup:
Output 3: DMX start universe: 3 , DMX Start channel 1, Pixels connected: 100, Null ; 0, zig: 0, intensity:100
Output 4: DMX start universe: 3 , DMX Start channel 301, Pixels connected: 47, Null ; 0, zig: 0, intensity:100

Xlights matrix setup:
direction: Horizontal
Strings: 1
nodes: 147
strands: 7
Start location: Bottom right

Any ideas?
