Estimation of reference cell type signatures (NB regression) functıon update not giving same results after mod train

[Nurik-ff]

Change was made according to cell2location guideline in preparation of anndata for regression model
from previously mentioned function:
scvi.data.setup_anndata(adata=adata_ref,
# 10X reaction / sample / batch
batch_key='donor',
# cell type, covariate used for constructing signatures
labels_key='Cluster'
# multiplicative technical effects (platform, 3' vs 5', donor effect)
)
to:

cell2location.models.RegressionModel.setup_anndata(adata=adata_ref,
# 10X reaction / sample / batch
batch_key='donor',
# cell type, covariate used for constructing signatures
labels_key='Cluster'
# multiplicative technical effects (platform, 3' vs 5', donor effect)
)

However, obtained results differ after mod.train(). Might it be that changes in the function might be causing difference in results? If there are changes in default parameters of the functions? Would you please help me with this problem.

Additionally wanted to say that we used cell2location 0.7a version in previous run
