Tile Slicer Data Label formatting

Hi michaelu1 ,

Based on the above information, It's a reproducible issue. 

I would suggest opening a Support Ticket, the Ticket Support Engineer will report this issue to the product team for you. If you are a Power BI Pro or Fabric licensee, you can create a support ticket for free and a dedicated Microsoft engineer will come to solve the problem for you. 
It would be great if you continue to share in this issue to help others with similar problems after you know the root cause or solution.

For how to create a support ticket, please refer to How to create a support ticket in Power BI - Microsoft Power BI Community

Anonymous I submitted the ticket, thank you.

I am curious though, isn't this the forum for submitting issues? Especially since this is a reproducible bug why would this require a separate ticket?

Hi michaelu1 ,

Unfortunately, due to bug feedback process adjustments, community support engineers no longer have the authority to report directly to the product team. We will test the issue raised by the user first and after ensuring that it is a reproducible issue will recommend the user to open a support ticket. If the issue is not reproducible or after our testing it is not an issue, we will first help the user to resolve the issue within the community. Thank you for your understanding.

Best Regards,
Community Support Team _ Caitlyn

I'm having the same issue as well. Trying to use some USD values (currency), but not getting the $ to show, and have many decimals despite setting to zero.

EDIT:  michaelu1 - if you're still looking for a solution, I was able to find a simple workaround at the link below.
