Absence of excitation energy value in list of generated particles

Hi There are presented two strings from List of generated particles after execution of Hadr06 example. In square brackets is value of the excitation energy (in keV) of the final-state nucleus (second string). Why there are no value of this energy in first string ?

Bi208: 226508 Emean = 17.833 keV|( 242.35 eV → 37.64 keV)

Bi208[1567.665]: 1 Emean = 25.85 keV( 25.85 keV → 25.85 keV)
