springboot ConfigurationProperties list Attribute is missing

When I have two remote profiles my version is 2.1.2 application.yaml: ```spring: cloud: gateway: routes: - id: cf_admin_route predicates: - Path=/admin/privilege/permission-tree/get-permission-tree uri: lb://cf-admin-api - id: sea_admin_route predicates: - Path=/admin/privilege/ uri: lb://sea-api - id: swagger_route predicates: - Path=/swagger/{segment}/ uri: lb://{segment} filters: - StripPrefix=2 - SetUri=lb://{segment} - id: health_route uri: forward:///actuator/health predicates: - Path=/health

application-test.yaml:

spring: cloud: gateway: routes: - id: im-server-socket predicates: - Path=/ws/cs-im uri: ws://im-server:9008 - id: kratos-api-web-socket predicates: - Path=/api/kratos/socketIo/wwChat uri: ws://kratos-api.zelda:9008

I will lose the following configuration：

    - id: swagger_route
      predicates:
        - Path=/swagger/{segment}/**
      uri: lb://{segment}
      filters:
        - StripPrefix=2
        - SetUri=lb://{segment}
    - id: health_route
      uri: forward:///actuator/health
      predicates:
        - Path=/health

```

As described in the documentation, when lists are configured in more than one place, overriding works by replacing the entire list. It works this way as, if they were combined, it would not be possible to remove or interleave entries.
