Mark prices for Episode 19 items for Shock Jock are too high

So I went to the Episode 18/19/20 vendor to buy a new piece of gear. Unfortunately, all of the head/shoulders/hands/feet/face items cost two marks more than they're supposed to:

Head: 52 (should be 50)

Shoulders: 47 (should be 45)

Hands: 42 (should be 40)

Feet: 42 (should be 40)

Face: 22 (should be 20)
