Hi @Cathy Yan,
Thank you for contacting us.
I would like to provide you with the following information:
You mentioned that the issue only occurs with Excel, while the connection works normally when using Power BI. Please try the methods below to check whether the issue can be resolved:
Method 1: Remove and reconfigure the connection in Excel Please try deleting the current connection and setting it up again in Excel.
Method 2: Clear Excel cache In some cases, Excel may store outdated information in its cache, which can cause data to display incorrectly or be duplicated.
- Step 1: Select File > Options
- Step 2: Go to Save, scroll down to Cache Settings, and select Delete cache files

If the issue persists after trying both methods above, I recommend contacting Microsoft Technical Support so they can perform a more in-depth investigation of this case.
