I just submitted a new entry and somehow two DB records got created in a single operation.
It's very possible my finger did something like a double tap on the submit button to cause this.
Oddly, both records are sequential and identical EXCEPT only the second (larger id) has the screenshot.
DUPE:

GOOD:
