Expedition Navigation Software / lamma model and italiameteo icon model

Hi

I would like to report a bug.

using squid I noticed that the system gets confused between the gfs model and the lamma model which is quite used in Italy

The Lamma model is a local interpretation of the GFS model made by the Lamma consortium

when I download the model I find the file in the grib folder called SQ_Lamm_45 etc but I don't find it in the wind model section

I tried to disable the original GFS model on Weather Data and I noticed that it still remains in the Wind Model section and is attributed to the Lamma model.

I believe that, being an interpretation, it creates confusion between the American GFS and the GFS interpreted by the Lamma consortium.

I noticed another small bug.

The italiameteo icon model, which is an interpretation of icon made by the Italia Meteo company, once downloaded is called Rome 255 62 in the wind models section

Thanks. I will add the Italia Meteo ICON to the known models list.

There isn't anything I can do if the Lamma model is coded as GFS.

Is this from Squid? They seem to default to coding data as GFS.
