Silman's chess ending manual

in Silman's chess ending manual
in the tests, in the section for players around 1500, the problem 9, the solution is wrong....
Am I correct ?

Did you check the eratta sheet?

thx, it is included in the erata...
I spent about half an hour on this problem, before checking it with an engine to see that I am right...
Anyway, at least I learned something...this Philidor defence(in R versus R+p) is not that mechanical as Silman's pretends...you still have to be carefull regarding some tricks...
