Why i can't update a realmObject that has a realmList inside it ? (I get an error)

Question

I want to update a RealmObject that contains RealmList and I faced this error : (look at the images)

So why I faced this error? and what's the solution?

Also why RealmObject has duplicate parameters (image 2)

My code and the error are below

InvoiceModel :

open class PurchaseDatabase : RealmObject {
    @PrimaryKey
    var id: Int? = 0
    var date: String? = ""
    var supplier: String? = ""
    var products: RealmList<ProductBuyModel> = realmListOf()
    var totalPrice: Int? = 0
    var paymentMethod: String? = ""
    var paymentPrice: Int? = 0
    var restPrice: Int? = 0
}

Error :
