I have a swap that says "failed". Not sure how to check any lower Nonces. I don't think there are any, because it would alert me right?

I found it the "nonce Position 13 Pending" that means you have nonce position #12 still pending or replaced it should be confirm first before the latest txt can proceed. this transaction is the main reason why its pending., https://etherscan.io/tx/0x9540788afdd8e02e8ea055825d4b0a0dfa3db6a7b80ad1d2ee7f2ce0f2cda504
