Your problem is occurring because you've tried to manually enter your tuning information in your capture source channel list. Delete your capture source, and recreate it, and this time make sure you do the 'map digital channels to epg channels' step.
On the left of the 'map digital channels to epg channels' you need to click on the 'tuning request' column of each of your EPG channels, and select which scanned digital channel it relates to. Any channels not mapped will be disabled.
