Wiring looks OK not 100% on the Kill switch whether the signal would follow the path of least resistance so I’d jumper it across from one side to the other lug 2 to 8 and leave the middle pole empty less chance of a dry joint
If you look at the schematic A and B would connect bypassing the LFO and sending signal back up to Q2 and OUT so I’m not totally sure if the jumpers you have would affect it in some way by connecting lug 5 to 4 as well I didn’t put the Kill switch option on my build so can’t really say

What Voltage readings did you get on the top and bottom of R7
