select all in Button slicer not Working Properly

Hi S_Manish ,

Thank you for reacahing out to Microsoft Fabric Community forum.

MFelix Thank you for your quick response.

That definitely sounds like an unexpected issue from your end. However, we're not experiencing the same behavior on our side. For your reference, please see the attached PBIX file which is working as expected in our environment.

To help resolve this, we recommend trying the following steps:

• Ensure you're using the latest version of the Power BI Desktop app.

• Make sure you're using the 64-bit version for better performance and stability.

• Fully uninstall and then reinstall the Power BI app.

If the issue still persists, I recommend raising a support ticket with Microsoft using the link below:

If this post helps, then please consider Accepting as solution to help the other members find it more quickly, don't forget to give a "Kudos" – I’d truly appreciate it!
