Sell order filled at very low price


I’d like to understand one order that seem like it filled at an erroneous price.
The ticker is AFBI, the sell order filled at 2021-08-26 06:30:06 at $5.42.
From what I can see AFBI hasn’t dropped under $13 since mid July. Any idea what could have happened?

Thank you
