Incorrect From address recorded in log

I have FluentSMTP configured with five different “From” addresses. Emails seem to be initially sent out from the correct address, but it seems that many of them are recorded in the Email Log as being sent from another address (the most recently added one). If I click “Resend” for one of those in the log, the new message is sent from the incorrect address. This seems to have been happening since September 2023. Is there a way to fix this?
