In several previous post has been commented that
"The unstandardized scores are in the same scale of your indicators"
But in my case, the latent variable scores (unstandardized) (INDEX in standard report) are slightly different. It is not a big difference but it is hard to explain in a descriptive report that the variables are measured in a 0 to 5 likert but latent variable scores have min= -0.489 and max= 5.910
