Take the wires of the switchbock and see if you still measure that DC path.
Than examen the DC path of both circuits if you can find a leaky path to GND.

Do you know how should I read the SK diagrams? The bold vertical lines, do they indicate connections when the switch is ON or OFF? When the switch changes state, would the bold vertical lines move up (for example, changing the connection from 5-6 to 6-7 on SK4)? Being able to read these switch diagrams would help understanding the intended DC path.

Indeed the bold blocks are the moving contacts.
They shift 1 position and all blocks mounted on 1 shaft or moving pertinax.

Similar to be seen on this bunch of switching parts.

Mostly right a single row contact with 2 times switching contacts.
Just left of that one a 3 row moving contact block.
Left of that one again the moving part.
Total on the left the stationairy parts of the switch block connecting the wires.
Shown at the sliding contact face.
