Demantra - series to show forecasting models is giving confusing results

Demantra - series to show forecasting models is giving confusing results

We setup series for engine models used and All enabled engine models. 

Engine Models Used min(mdp_matrix.models)

All Enabled Forecast Engine Models min(mdp_matrix.demodel)

At the lowest level, we are seeing strange results. 

The identifier for Engine model used is a number, for all enabled forecast engine models, it is a letter. Why? How do we tell which models? 

We expected the all enabled forecast engine models to be the same across all combinations, but it is not. Why?

Thanks
