This was caused by a bug.  For the data source, the list of times
shows all available times.  For an individual field, it should
show just the times for that field.  If you selected a field
like geopotential height anomaly, you would get the list of
all times.  If you then selected another field like geopotential
height, you would see just the times for that field.  If you then
went back to the geopotential height anomaly, you'd get the
correct times.  We have fixed this problem in the latest nightly
build so that the correct times are shown on the first selection.  
Thanks for noticing it.  There is an albedo field that has the
hourly time fields right at the beginning.   I think these are
being filed incorrectly and will look into removing them.

I'll look into this on Monday.  Is it always the same forecast
period that is missing (e.g days 6 and 7)?

Some of this is code, the other is most likely a wrong pattern
action in the LDM.
