There are two reasons: 1. Credit cards cooperate with websites or businesses, and a single transaction is limited. If it exceeds this limit, it will be divided into two transactions; 2. Credit card banks are also limited in a single amount.

Solution: 1 Pay by credit card instead of credit card, or by cash or savings card; 2. Place an order twice for transaction payment.

There are many reasons for this problem, don't panic.
