Bubble Size on Map

Hi BI Community Team,

When I drag and drop the Total_Sales column into Bubble Size field then bubble on map are showing only the customer that have order (amount).

Any suggestion/advise to show for both with specific color -- customer have Order is Red and No order is "Green"?

Here is the sample pbix file - https://drive.google.com/drive/folders/1sVoWOQRvw6fMc_CG3a6k2i1PvgEtVM6n?usp=sharing 

Thanks and Regards,
