Duplicate sqlth_te entries?

I was investigating some weird history query results today and stumbled on this fun tag:

MariaDB [ignition]> SELECT * FROM sqlth_te WHERE tagpath = 'edge nodes/demo/352656102543801/dev1/report count';

8 rows in set (0.122 sec)

I can explain the really old timestamps. That was our fault, generating malformed SparkplugB payloads.

I can’t explain the multiple entries.

Is this normal? How might this have happened? Does the historian query all of them when I ask for the history of that tag path?
