The resource model name isn't being translated when you execute a DB transaction (create, for example). The whole message is translated according to the yml file but the resource model name.
I believe the problem relies on ResourceReolver#resource_title, which just parses the current path and returns a joined string. The #translate_with_resource (the method that translated the message itself) should use ResourceReolver#resource_class combined with ActiveRecord locale methods to return the resource model name already localized to the message _translator_ method
This is the message that I'm getting

And my yml file does have that model translation entry
pt-BR:
activerecord:
models:
transaction_category:
one: 'Natureza de Transa莽茫o'
other: 'Naturezas de Transa莽茫o'
This problem is happening with other resources around my admin section
I've worked around this by overriding the #translate_With_resource method on my Admin::ApplicationController with the following
def translate_with_resource(key)
t(
"administrate.controller.#{key}",
resource: resource_class.model_name.human
)
end
But I still think that this should come by default
