Export of COUNT(Content: Nid) field is incomplete

When configuring a view with group by, the options form for a COUNT field uses the handler views_handler_field_numeric. However, when the view is exported some field_numeric specific settings are lost, because the COUNT field is exported with the handler views_handler_field_node in my case. Settings like format_plural, format_plural_singular, format_plural_plural etc. are not exported and lost. The view works fine, but the export is incomplete.

I have attached the export of my View.
