Symfony вставить несколько строк, вставленных в одну

У меня есть проводная ситуация здесь. При сохранении Symfony вставляет несколько записей вместо одной. Я не могу найти никаких проблем с моим кодом, и я не уверен, как отладить эту ошибку, потому что кажется, что все в порядке.

Логика приложения заключается в том, что пользователь может выбрать две автобусные станции и создать маршрут. Также ему нужно определить цену и группу (минимальное и максимальное количество людей). Кроме того, пользователь должен выбрать автобусные транспортные средства, которые будут ездить по этому конкретному маршруту

Кто-то знает, где проблема?

Вот вывод сущности при отправке формы

StationStandardPrice {#553 ▼
-id: null
-company: Company {#549 ▶}
-busVehicleGroupSize: BusVehicleGroupSize {#1233 ▶}
-departureStation: Stations {#1247 ▶}
-destinationStation: Stations {#1236 ▶}
-currency: Currencies {#1015 ▶ …2}
-price: 99.0
-busVehicles: ArrayCollection {#554 ▼
-elements: array:2 [▼
0 => BusVehicle {#1023 ▶}
1 => BusVehicle {#1208 ▶}
]
}
}

Это сущность маршрута (сокращенная версия)
