Is there any way to solve it?


The answer is Backfill and

Very thanks for answer! You mean forced backfill, if I want to handle it automatically, I have to use an external tool to operate?

I tested it and found that the backfill was correct, but when I closed the amibroker and opened it again, the error data came back and I needed to backfill it again. Is there a way to automatically backfill through AFL calls and store them in the database?
