Yes, I checked that… Have you ever had anyone with this issue? If no I will dig into it.

Nothing in our GitHub issues. Please let us know what you find. I bet it's an API change. Everyone has been implementing LNDHub slightly differently and it's been causing problems.
Years later I can confirm that it is indeed an LNBank (BTCPay plugin) bug, probably unrelated to Zeus. Zeus correctly displays outgoing payments on the LNDHub implementation of lnbits.
