Excel Sheet Overriding Issue Fix

I am experiencing a frustrating issue with my Excel file that tracks mileage numbers. After updating to Excel 2019/365, the sheet keeps overriding the numbers I input.

I need someone who can:
- Troubleshoot and fix this overriding issue
- Ensure the sheet accurately records the data

Ideal skills for this task include:
- Proficiency in Excel, particularly in 2019/365
- Experience with troubleshooting Excel issues post-update
- Knowledge in mileage tracking spreadsheets
