This sometimes happens because of how the OVERLAY keyword works - if you
specify OVERLAY on a record format, other formats that are not overlapped
will not be erased.  I suspect you have OVERLAY on all your record formats,
and none of them overlap the subfile, so the old subfile is not being
erased.

If this is the case, you can do one of the following when there are no
records:

1. Make sure that you write at least one record format WITHOUT using the
OVERLAY keyword (condition the OVERLAY with the same indicator that you use
to condition SFLDSP).  This will erase the entire screen.  This option may
be the easiest, depending on your screen layout.

2. Write a dummy format that occupies the same space as the subfile.  This
is actually a nice option, because you can output a nice "no records found"
message.
