Looks like your cable provider does not have channels below 100 in the channel map they send to the CableCARD. This either means that they don't carry channels below 100 in digital format at all, or they are using switched digital video (SDV) and you'll need a tuning adapter to receive them. I've never seen a provider that actually put the basic channels on SDV, but I have seen some screw up the lineup they send to the card and leave out channels that should be there. You could probably get them to fix it if you could actually reach someone who knew anything about SDV (yeah right), but it would be easier to just get a tuning adapter, which will get the correct channel lineup.
