A synchronization problem on WPF mobile application

I am using ArcGIS Runtime SDK for .NET WPF 100.2 to develop mobile applications. I got a problem on “synchronize” function. When the app generates an offline database and then collect data, it works well, but the new collected data cannot be synchronized to our geodatabase when I press the “Synchronize” button. For the Synchronized function, I am using the code in this sample The synchronization is successful, but I cannot find the new data in our geodatabase. However, after I edit these new data(such as changing some attributes’ values), it can be synchronized to geodatabase. It seems like “synchronize’ cannot identify new data, but edited data. Is it normal? In my code, the SyncDirection is Bidirectional, I run the code step by step and the synchronize always finished successfully. Does who know what reason causes this problem? How I fix it? Thanks
