Leaving container type blank on a top container results in a translation missing display in the badge for the item it's linked to in the public interface

If container type is left blank on a top container (which is fine - container type is optional), the badge in the public interface displays "translation missing: en.enumerations.container_type.container:" between the level of description and the indicator text. According to reports, this behavior appears to have changed sometime between 2.6.0 and 2.8.1. Previously only the level of description and indicator would display.
