Are you sure you’re seeing your downlink (something with a payload), not some attempt from TTN to send some ADR commands (maybe without an application payload)?
And scheduling set to “replace”? Did you ever have “confirmed” checked? (Don’t if you didn’t.)
And the uplink and downlink counters. (And use ttnctl to set those.) But: I’ve never tried it. Deleting stuff in TTN Console is scary…
