Date field changes after publishing a report into Power BI Service

I'm wondering if someone experienced this.

1. In Power BI Desktop, a table visual shows transaction id "123456" and its Date1 field:

Transaction ID    Date1

123456       

In other words, Date1 value is blank

2. In the Query Editor, same value is shown as:

1/1/0001 12:00:00 AM

3. In the data source (CRM system), same value is stored as 

4. When published to the Power Bi Service, same value is shown as:

12/30/1899 - this behavior throws off my calculations

I need to keep the field as date data type simply because I'm doing datediff calculations. My goal is to keep it to blank just like Power BI Desktop shows(1.)

Any suggestions?
