Hi Nataliia_RWE,
Welcome to Community! I'm happy to hear that you were able to successfully edit your service item. Time data automatically syncs to your QuickBooks account, so any changes you make are updated in real-time, keeping your data accurate. However, based on the information you've provided, I recommend contacting us outside of Community. This way, we can review the unexpected outcome in more depth, and ensure your QuickBooks goals are accomplished as soon as possible!
If you have any other questions, feel free to reach out. We would be glad to help!
