Hey XZenGifts sorry to hear you are having this issue. First, have you used that Aliexpress account for personal orders in the past? If so, those previous orders for yourself will be causing this error.
If you have not used Aliexpress for personal orders in the past, then it might be something else. However, I would not be able to see why that might be without accessing your store. Please email our support at email@example.com so they can have a closer look!
