For the rollovers, what is the pitch of your playfield? If it's not steep enough, that can happen. It doesn't look like the rubber is touching it. HOWEVER if someone shopped it, they may have put the wrong size rubbers on the posts. The top and bottom ARE NOT SUPPOSED TO BE THE SAME. Top are 3/16", bottom are 5/16" and the one on the far right lower should be 3/4".
On the second one that cannon cable has a cutout where the plastic ends right above where it's resting now, I think. There should also be two clips on the side of the cannon that hold the cable close to it until it guides the cable into that empty cutout space. You should be able to move the cable up and into that spot to hold it out of the way.
If you're missing the two white clips on the side of the cannon to hold the cable, that could be your problem. If you take the screw off on the end of that ramp so you can move it out of the way, you can take a better pic of the side of the cannon.
AC/DC Luci isn't an LE, BTW. It's a Premium or a Vault Premium.
