Missing column description after control record with ID &1.

What causes this issue?

During the import of data from the presentation server, the system read
a new control record. The control record contains structure &V1& for
data lines, together with the number of data records that exist for it.
The next line, &V2&, is supposed to contain the column heading for the
data lines which follow. These are fields of structure &V1& that were
selected for the columns of the data lines.
However, line &V2& with its expected column description does not exist
in the file.
