Fix Data Saving in Steam Tool

I am in Stage 3 of my Steam NPS Tool and have hit a blocking issue on the data-processing side: records frequently fail to save, even when no API calls have yet been made. The core logic is written and the UI is stable, so the assignment is focused purely on tightening up the persistence layer and then re-running our historical data through the existing API endpoints.

What I need you to do
• Trace and resolve the “data not saving correctly” bug in the current codebase.
• Once fixed, trigger the back-data processing routine so every past record is pushed through the same API flow and stored reliably.
• Provide a short report outlining the root cause and the exact code changes (file and line references) so I can merge confidently.

The project is housed in a private Git repo. You’ll receive access along with a sample data set and API keys. I’m ready to test your patch immediately, so please be comfortable working in a quick feedback loop and writing clean, well-commented code.
