Requality

При изменении имени тестовой ситуации изменения не всегда сразу отображаются в Requality Explorer. Иногда такие изменения не сохраняются.
Пример 1.
1. Создаем тестовую ситуацию.
2. В Properties view указываем ее имя.
В Requality Explorer видим идентификатор тестовой ситуации, как будто имя не указано.
3. Кликаем в Requality Explorer на какой-нибудь другой узел, потом кликаем основа на тестовой ситуации.
В Error log ошибка:

Видим, что в Requality Explorer теперь отображается указанное имя тестовой ситуации.
4. Зарываем проект и открываем.
5. Видим, что у тестовой ситуации в свойствах имя не указано. И она отображается по идентификатору.
