SOS!!!!

Hi all,
back onto Hot Tip.... in our last episode, I could play a game and every so often, the drop targets were found to be resetting twice before a ball due to switches on the Bonus Unit not making proper contact.

Yesterday I decided to get back onto finalising the machine and adjusted switches with the switch adjuster tool by giving them a slight bend. I have now spent two afternoons adjusting and re-adjusting switches and cannot play a single game due to either switches not making proper contact to eject the ball or switches being too close that the drop targets continually reset until I have to turn the machine off. I am now at a point of total loss to understand why it's doing what it is doing. Can someone please point me in the right direction?

I have included a picture of how I think the switches should be at zero position and position 1. Can anyone see what I'm doing wrong?

Thanks,
Adam.
