## Description

```

## Current Behavior

Some commands are being logged twice in `nsp_outputs.csv` from Turk interaction sessions. Strangely, the command without processing also has model outputs where span values are wrong. Need to debug further whether model is queried twice (why), if so why commands with punctuation cause span values to break, and why this only happens on some commands.

## Expected Behavior

one record for each chat sent in the logs
