Interface Profile "Interface | Broadcast | In"

Steps to reproduce

1. Interface Profile - добавляем метрику "Interface | Broadcast | In"

2. Не выбирая никаких checkbox'ов (Box, Periodic...), нажимаем Save.

What is the current bug behavior?

Получаем Error saving record и невозможность просмотреть общий список профилей и как следствие исправить/удалить проблемную метрику. Приходится лезть в mongo и удалять руками.

Relevant logs and/or screenshots
