Additional predicted levels (EVID=2) changed objective function values

Dear NMusers,

I intended to print out more predicted levels at the time points without ob=
servations. Therefore I inserted those lines with EVID=2 in the data set.=
 Surprisingly after doing so, the objective function value and the fitted p=
arameter values changed more or less. This should not be rational. Could an=
yone explain the reason and how to avoid it? Thanks a lot in advance!

Best regards?
