Hello, my SKU has been lost. It's a very serious problem. Please help me solve it.

Hello, here's the thing. Yesterday, when I modified the price in the background editing interface, he reminded me that the price set was too high. I'm worried that the price change will not be successful. So, I clicked on the BIL price next to it and entered the international information interface. I found that the site that I had not been associated with before suddenly showed the association, and the source mall was BE, so I removed the association, but less than half an hour passed. Nearly 80 SKUs in my German site are out of stock, and most of the remaining SKUs are missing from quotations and are not displayed. I went to the front desk to check that my goods were all lost in the shopping cart. Why is this? I thought that the establishment of international information was only related to the price between sites, and why was it also related to asin? I don't want to delete my asin. How can I recover it quickly? This is a very, very serious problem for me. Please help me check the problem and the solution. Thank you!
