NVMe error information log entries

My weekly status report e-mail highlights these NVMe errors but I can’t find any details on them (or I’m looking in the wrong place…).

Can anyone shed some light on where these come from? The smart output seems rather contradictory.

Media and Data Integrity Errors: 0
Error Information Log Entries: 6
