Actually, I think it is correctly wired in V3 but V4 still seems incorrect.

I checked again and it seems grounded to me. Again, this might be a problem with the ground plane not being shown in the picture. If you look at the circuit diagram, the mono jack is grounded. The ground plane was newly included in V3 and V4, which was not there in V1 and V2. However, when I took the pictures, I omitted a rats-nest trace of the V+ and Gnd planes, since everything just looked purple. I will replace the pictures for clarification as soon as I can.
