Mine was missing too until I did something, I'm not sure exactly what I did, but it might have been this. No harm in trying it if your Best of Bandon CTTH game option is missing too.
EDIT : I appear to have entered a Best of Bandon sweeps tournament as well, which may have brought the CTTH game option back too.
