oh man now that can be a cause of worry....coz if its showing nothing in the "date box", then it can mean that they haven't even picked up ur file yet...i mean they haven't initiated the processing of ur file....
now this is what usually happens...but other optimist view can be that they sometimes don't bother to update the file status or rather forget
(which i must say is slightly unusual)
Wat i suggest is that either u try to contact someone real soon and get some info about ur file or as i said earlier...pay them a visit..
all d very best!!
