What Does "Failure of Duty" Mean in Dismissed Charges

[StormRider]

My question involves criminal law for the state of: Indiana

What does Failure of Duty mean on the docket entry of dismissed charges? The jury trial was set to begin today and the docket entry reads that charges were dismissed and the action description is "Failure of Duty" dated in August. This trial still showed as taking place last Thursday.

We don't know anything about the trial or docket, or what orders may or may not have been entered. We have no access to the court file. Your guess is much better than ours.
