Substantial differences in output "mplus" / "mclust"

[Fabio Trecca]

Hi,

I have noticed that estimate_profiles()  gives very different results depending on whether I use package = "mclust" or package = "mplus". 

Here are the results of the Mclust estimation:

And here is the Mplus estimation:

The relative distributions of individuals in the three profiles are the following:

Mclust: 1=102, 2=67, 3=13

Mplus: 1=114, 2=53, 3=13

I understand that differences are to be expected since Mplus uses random start whereas Mclust uses hierarchical clustering, but the differences I get are huge. 

Here is the syntax I use:

lpa <- df %>%

    select(vars1) %>%

    scale() %>%

    estimate_profiles(3, package = "mclust", select_vars = c(vars2))

Can anyone help me figure this out?
