Difference between statsforecast.arima.AutoARIMA and statsforecast.models.AutoARIMA

[WilsonDog]

I use the same input data and almost the same set of parameters for statsforecast.**arima**.AutoARIMA and for statsforecast.**models**.AutoARIMA and get different results. The only difference is that for the "arima" submodule, I specify period=12, while with the "models" submodule, I chose season_length=12 (there is no "period" argument). Everything else is the same.

After fitting the models, I compared the "arma" results of the best models, and I got different results, but none of them matched R's forecast results. Moreover, in the "arma", I see "1" in the periodicity instead of "12", even though I ask for a seasonal version each time (seasonal=True).

If that is already scheduled for change in the #497 issue, then I would like to know which version will be the final and why the periodicity is not displayed.

Thank you
