I think it may be something going on at Greenfield. I just tried to take the SM one for the first time in a couple of days and there are no options for me either. Hopefully tomorrow it will be back to normal. My DH has never had a problem getting the regular DS. I do sometimes have trouble getting a SM one, but not when I haven't done one in a few days. That's why I'm thinking this is a glitch of some sort.
