[ferret_users] sampelij generates wrong missing values

I have a data file that has missing values defined like

                temp:missing_value = -1.e+20f ;

Ferret 6.1 deals with this definition almost corrrectly. One exception is sampleij. Selecting data at some points with samplexy and writing them to a file gives correct missing values.
Using sampleij instead, missing and fill value is set to
               TEMP_IJ:missing_value = -1.e+34f ;
               TEMP_IJ:_FillValue = -1.e+34f ;

The original missing values are used as valid data now and additional measures are needed for a correct data treatment.
I think this is a bug?
The original data have also an attribute

               temp:valid_range = -10.f, 100.f ;

Does ferret read this?
