I have also the same issue. This goes for 11 vs A as well, where the software recommends hit at a true 0 in 6D, H17. Im sure theres a mistake somewhere in the settings, although I havent found it yet. And Im too lazy to bother Norm, since the difference in EV is pretty minuscule.
Speaking about CV issues, the machine never approves me surrendering 7-7. Every time when the count is +3 or higher and I make this play against the 10, the software reacts. It does not react when I surrender 8-6, and I have not hooked off any triple-7 bonuses or anything.
