Laravel 5.2 Many to Many Relationship inverse query empty results

I have 2 models DfpLineItem and DfpCreative

DfpLineItem model with relationship

    public function creatives()
    {
    return $this->belongsToMany('App\DfpCreative', 'dfp_licas', 'line_item_id', 'creative_id')
        ->withPivot('lica_data')
        ->withTimestamps();
    }

As you see this means pivot table is dfp_licas which already exists, also there is a timestamps columns and lica_data columns.

Everything is fine with this part. When I'm trying to get the data from DfpLineItem model, everything is fine and working as expected. For example

$lineItemData = DfpLineItem::findOrFail($id); related Creatives exists in this query result and I can access to them like $lineItemData->creatives.

Problem appears, when I'm trying to use inverse relationship. Here is my is the relationship defined in my DfpCreative model

    public function lineItems()
    {
    return $this->belongsToMany('App\DfpLineItem', 'dfp_licas', 'creative_id', 'line_item_id')
        ->withPivot('lica_data')
        ->withTimestamps();
    }

I think everything is find with this relationship, but when I'm trying to get data like below Id is hardcoded

    $orderData = DfpCreative::findOrFail(72174072858);
    dd($orderData->lineItems);

Getting empty results, but checked many times, records exists in my dfp_licas table. No Idea why this is happening.

Any help will appreciated.

Thanks
