Online opening book

I am well aware that with so many opening lines to keep track of mistakes must/will happen. However after this line, in the GM online book, two games are found with the move !5.f4! Yet in the online GM+ book the same two results are given 15.f4? Not really of much help.

1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 5.a4 Bf5 6.Ne5 Nbd7 7.Nxc4 Nb6 8.Ne5 a5 9.e3 Nbd7 10.Qb3 Nxe5 11.dxe5 Nd7 12.e4 Be6 13.Qxb7 Rb8 14.Qa7 Nxe5 *

This anomaly has been resolved and the GM+ book has been hugely updated for all Deep HIARCS Chess Explorer customers.
