The program failed to determine the width of the order traces.
The algorithm for this process requires that the intensity falls to less than the fraction TUNE_TWTHR of the intensity at the peak.
The parameter may be adjusted (probably increasing it), or specified directly using the FIGARO command
SETOBJ object=-rdctn-file-.MORE.ECHELLE.TRACE_WIDTH value=nn
where nn is the approximate width in pixels.
