Can't read number field where value is greater than 0

For some reasons, when I do a query request to get my objects, some properties of the json objects are missed. Below the query :

        data => {
            if(data.value) {
                Object.keys(data.value).forEach(key => {
                    this.results.push(data.value[key]); // Here I dont get exactly the JSON, some properties disapears.....
                }
            }
        }, "/ads/", 
        { orderBy: { type: firebase.QueryOrderByType.KEY }})
        .then(result => { return result; })
    );

Properties of type number are not loaded (totalProduct and state) when value is greater than 0.

holy cow. That seems to have done it! Wow, what a strange behavior!! But thank you @eddy and @fsandreau I hope this might help you!!

I’ve created a sample using both query and adding an event listener. Consistently, when I run the app using tns run ios I get my data back, but when I use tns livesync ios --watch nothing is returned. I would just say, ok, don’t use livesync, but I am not convinced that this same problem doesn’t occur when I build to device (tns deploy ios --device device-id), close the app, and then reopen it.
