Quantities of items are not tracked in google analytics transactions

问题

I'm trying to send e-commerce transactions from my iOS app using google tag manager like described here

Now I can see transactions in the conversions > e-commerce > overview panel in google analytics but all the items have a quantity of 0.

I'm making a NSMutableDictionary for the items like so:

for (CartItem *item in cart.items) {

    [transaction[@"transactionProducts"] addObject:@{@"name": item.productName,
                                                     @"sku": item.reference,
                                                     @"category": @"mobile",
                                                     @"price": item.shopPrice,
                                                     @"currency": @"EUR",
                                                     @"quantity": item.quantity}];
}

item.quantity is a NSNumber

In analytics I can see the name, sku, category, price but NOT the quantity.

Am I doing anything wrong ?

EDIT:

I enabled verbose logging in the GA library so I'm able to see everything that's sent to analytics. For instance, I made a transaction with an item with quantity = 1.

In the logs I can see :

    gaiVersion = "3.03";
};
timestamp = "2014-03-21 07:51:35 +0000";

}

    "&iv" = mobile;
    "&sr" = 320x480;
    "&t" = item;
    "&ti" = "6753864 - 3240";
    "&tid" = "UA-XXXXXXX-X";
    "&ul" = en;
    "&v" = 1;
    "&z" = 9238494410774743126;
    gaiVersion = "3.03";
};
timestamp = "2014-03-21 07:51:35 +0000";

}

I can also see that the dispatch works.

I'm unable to reproduce the problem on my end.

Can you post the entire set of parameters that are being sent in the GA hit in order to help me diagnose the problem?

This issue was due to a bug in the library and has been fixed in the version 3.0.7 of the SDK
