When following the recommended implementation for field level translations, the translation fields are stored in a fieldset. If only the default language is selected, I expect the fieldset to be hidden, as there are no fields to be displayed.
While this can be implemented manually, I would expect this to be part of this plugin.
Screenshots
The first screenshot shows the behavior for a scenario where all (or at least one) language is selected.
As shown below, the fieldset legend is still visible, if no fields are displayed.
The expected behavior would be the removal of the fieldset, as demonstrated in the screenshot below.
