It is pretty normal for bears to be far ranging during the summer and early fall months. As time goes on in the fall, they restrict their travels to increasingly smaller areas around their winter den sites.
I'm guessing their is a large likelihood that the family groups you were seeing last year drifted back to their den areas and went up for the winter. Since bears under 75# and sows with cubs at side are not legal for take, I'm betting they aren't part of the harvest report. Once they come out from their dens in the new few months, you may see them again as they range out.
