Hi there, clong1.

Let's try a few troubleshooting steps to check if this is a cache related-issue.

1. Use the private window to check if you can save time tracking user.
2. If you can, go back to the main browser and clear the cache.
3. If you're still experiencing the same issue, try using different browsers such as Mozilla Firefox, Google Chrome or Internet Explorer.

Let me know if it works.
