If you have a multimeter handy, you might check to see if there’s a short circuit between lines LED1 and LED2, or between either of those lines and LED10. There could be a solder blob or stray wire somewhere causing the problem. I’m having a little trouble following most of your specific LED locations, but that would be my guess from your description on the red ring.
The Zerohm jumpers really are a specific type of wire jumper. They are not actually resistors; we did not choose them “instead” of wire jumpers. They are inexpensive, easy to count out, convenient, easy to identify, and their shape makes step 33 of the instructions pretty easy. Without that “bead” in the middle, we’d need to figure out some other way to hold them in place, and make sure that there was enough length on both sides.
