请问No position matches是什么问题引起的？

[cJie-sg]

/month/2025-02.bean:19: No position matches "Posting(account='Assets:Flow:EBank:WxPay:微信支付', units=-334.61 CNY, cost=CostSpec(number_per=Decimal('0.2'), number_total=None, currency='SGD', date=None, label=None, merge=False), price=None, flag=None, meta={'filename': '/data/beancount/886838d8d019d7e69d3fd95ea49d7e89a9526ece/month/2025-02.bean', 'lineno': 20})" against balance (1.03 CNY {1 SGD, 2025-01-15}, 1500.00 CNY {1 SGD, 2025-01-28})

2025-02-03 * "微信红包" "发微信红包"
Assets:Flow:EBank:WxPay:微信支付 -334.61 CNY {0.2 SGD}
Expenses:Life:Other:Exchange:红包转账 66.92 SGD

之前也是碰到过，后面我i只好把前面的删除掉重新再一次添加，一直不明白是什么原因引起的该错误。
