RealmList Bug

/*Realm incorrect nested managed RealmList BUG*/

public class ProductOption extends RealmObject {
    @PrimaryKey private String uniqueId;
    private long id;
    private String title;
    private int format;
    private Product product;
    private RealmList<ProductSubOption> suboptions;
  	//Getters ans detters are here
}

public class ProductSubOption extends RealmObject {
    @PrimaryKey private String uniqueId;
    private long id;
    private String name;
    private double price;
    private String description;
    private ProductOption option;
  	//Getters ans detters are here 
}

/*Way of adding items to Realm is:*/
for (ProductOptionModel opt : p.getOptions()) {
    ProductOption productOption = new ProductOption();
    //call setters
    mRealm.copyToRealmOrUpdate(productOption)
    for (ProductSubOptionModel subOpt : opt.getSubOptions()) {
        ProductSubOption productSubOption = new ProductSubOption();
        //call setters
        mRealm.copyToRealmOrUpdate(productSubOption);
    }
}

/*Way of fetching options and suboptions*/
RealmResults<ProductOption> options = mRealm
    .where(ProductOption.class)
    .equalTo("product.id", productId)
    .findAll();
int i = ...; //any valid number here
options.get(i).getSubOptions(); // !!! ISSUE HERE !!! instead of getting e.g. 6 elements just 5 returned

/*If to query ProductSubOption separately everything OK*/
int someOptionsId = ...;
RealmResults<ProductSubOption> subOptions = mRealm
    .where(ProductSubOption.class)
    .equalTo("option.id", someOptionsId)
    .findAll();
 
 /*In this case result is correct. All items returned*/
 subOptions.size() == 6
