1. Have you added any custom entries into your order status config in ZC? Or possibly reordered the entries in any order status related DB tables?
2. When you originally shipped these specific GC orders are you changing order status to "Google Shipped" rather than "shipped"?
And if you are cancelling the complete order AFTER shipping then you should choose "Google Refunded"
But if you are cancelling order BEFORE shipping. In that case you should choose "Google Cancelled".
(if you are cancelling only a part of the order then you need to log into GC account and refund a partial order amount)
