An error in Polgar's book of chess problems

Laszlo Polgar has written a huge book of Chess problems, called Chess: 5334 Problems, Combinations, and Games. I've had it over ten years now, doing problems every now and then. After recently finishing the 1000th problem, I realized I had better quicken my pace or I won't finish the book until I'm in my 80's. I'm now trying to do a page a day, at least most days. Today I came across problem 1071, which is the first problem I've found that is misdescribed. It is supposed to be a mate-in-two, but it is a mate-in-one. To make sure that I wasn't missing something, I double checked it by setting up the position in Zillions-of-Games. I then copied the position into a Chess preset for Game Courier, which may be viewed here.
