Hello,
Unless there are stored (or "pre-calculated") contours left over from the
first time the spectrum was opened (and I don't think anybody would
calculate stored contours for a 2D data file) then this should not result
in a double image. So if the spectrum had (just) been reprocessed (or
whatever) at worst that would show a shifted spectrum and not a double
spectrum (unless the reprocessing itself went wonky).
