Neo4J-Spring Boot

Question

Контекст: Java-приложение с пружинной загрузкой и neo4j для бэкенда и угловым 5 для внешнего интерфейса.

Проблема, которую нужно решить: Когда я сохраняю объект US, который может иметь 3 разных типа отношений сдругие случаи США стирают отношения его ребенка. Пример:

• US1
• US2
• US3

US2 синхронно с US3 .Если я поставлю US1 перед US3 , соотношение между US2 и US3 исчезнет.

Вопрос в том,есть конфигурация или способ предотвратить это?
