NTDA Displays Confusing Legend Shortly After New Radar Slice

When a new radar slice loads into AWIPS, NTDA takes several seconds to load in on top of it. The legend displays “NO DETECTIONS Not Loaded”, and there are no symbols on NTDA symbols on the radar map. The no detections in this case can be confusing, since it really means the product has not loaded in yet for the valid time.
