I see what I did. I put the foil tape to far up the heat, and it was touching the copper plating resulting in me getting a nice jolt. RBI emailed me back confirming it too. Now comes the fun part of re-taping shelves with less than a foot of work room! I'm going to insulate it first with electrical tape and then go over that with the foil tape, making sure its not touching anything. God I feel so dumb right now!
