Not recorded, no signal, live tv ok

New roamio connected to antenna only was recording season passes correctly before this week. It stopped recording some OTA channel season passes this week, stating no signal, not recorded in the history, However, live tv on those channels is fine as is the signal strength meter. Other channels have working season passes. Restarted, still a problem. Outdoor antenna is not split.

If I repeat guided setup, do I Have to redo all season passes? Why are channels that are obviously working not getting recognized? Any solutions?
