Intercepts when using R3STEP PreviousNext

Hi! I am using Mplus version 7, and would like to regress a latent class variable (6 classes) on age (3 age groups, coded with 2 dummies agecat1 and agecat2). I tried using R3STEP with the following syntax:

CLASSES = c(5);
AUXILIARY = (R3STEP) agecat1 agecat2;

The output gave coefficients for c#1 to c#5 ON agecat1 and agecat2, but not intercepts. For interpretation, I would like to translate these into proportions (e.g., among people in age group 1, which % are in each class), so I need both the coefficients and the intercepts. Is there a way to ask for intercepts in the output?

(When I run the one-step model with c ON agecat1 agecat2, the output includes both coefficients and intercepts.)

Thank you.

Download Version 7.11. I believe there was a change and intercepts were added.
