When the ball goes through the Right in-lane (Switch 17) then also Right out-lane (Switch 18) triggers in the switch test. The other way around too.

If I disconnect the 2-wire in-lane Proximity sensor from the board, the switch-test says Right Out-lane. There is no reaction if I touch the Out-lane switch when the In-lane Proximity sensor is disconnected from the board.

Both the Right In-lane (Switch 17) and Right Out-lane (Switch 18) are triggered if I disconnect the 4-wire power from the in-lane Proximity board and I touch the Right Out-lane.

How could that be possible? What steps should I take to resolve this?

The switch matrix thinks switches are activated when the wires in the x/y crossing are shorted. So for it to think 17 and 18 are both activated, it would see a short for Green-Brown, White-Violet and White-Gray. What's odd is that if you had two row wires shorted, then you'd see similar behavior across all column 7/8 switches, like Center 45 target and Right 45 target. But maybe you have damaged wires and it's the power connector for the eddy board and the white-gray (sw 18) wire. Can't really explain the behavior but suggest you look for damaged wires in the area. You can also do continuity checks and look for shorts.
