Is seems strange that LND sends two HTLCs with identical amount and hash but different expiry.

I'm in contact with remote LND operator, what can I ask them to do in order to get more useful info?

@btcontract this is a known issue that has a proposed solution in the rfc.

it's probably the case that LND is forwarding those htlcs, instead of sending them directly. recent versions of LND disallow making multiple concurrent payments to the same payment hash as the sender

Yes, this is the case.
