Afternoon, jing-li,

I encourage you to contact our QuickBooks Desktop Technical Support Team. They have the tools to do a remote session and investigate this further.

Here's how you can contact our customer support:

1. Select QuickBooks Desktop Help from the Help menu.
2. You can also press F1 on your keyboard to bring up the same Help Panel. 
3. In order to route you to the correct support expert, we need to know what type of question you have.
4. Click Continue.
5. We’ll provide you a few options. You choose which one is best for you. 

Please let me know how it goes. I'll be here to keep helping if you have any other concerns. Have a good one.
