First off the Clock divider you are using is weird. It starts on the second gate of the clock and it divides in a weird way f.i. divided by 5 (the 5 output) will produce a gate not every 5 steps but the first time after 5 steps then it continues to 8 ( three more steps) and then it starts to count until five again. So its really a divided by 8 ( where the first step starts at 5) the /7 is the same starting at the 7th which is the eight, because it skips the first step.
The one next to it (Ohmer) works as expected, it starts at 1 and the /5 output gives you a gate , every 5 steps. (and yes the gate is “only” 5V)
And this is an Xor gate.
And here is /3 you get 1,2,-3-, 1,2,-3-,1,2,1,2,-3-, 1,2,-3-,1,2,1,2,( starting on the second step)
And it should be like this :
