I'm experimenting an issue when I export customizations made by Studio tool, any custom fields are not exporting. I mean, when I load the package created in developer server to the production server, there are not custom fields in EditView, there are "native" fields only.
I'm using SugarCRM 6.1.6 (I know, it is an old version, but I can't update it right now)
