How do I accurately set location for eBay dropshipping inventory?

How do i set location for dropshipping inventory that is in china on the ebay sales channel?

-The drop down defaults back to my us address every time.

-If i change inventory location in sync settings, an error message pops up when publishing: failed listing because inventory location does not match site.

With an incorrect location, shipping times and estimations for customers on ebay are not accurate which leads to significant returns and customer service issues.

Thank you!

I have the same problem. I had to put my US address for returns on ebay and now I have a return and my Chinese supplier is not going to get it back for a longer time.
