Small Multiples - Wrong data labels

Hi agnesj,

Thank you for confirming. Based on feedback from multiple users, it appears this issue is a limitation or bug in how Power BI currently renders data labels within small multiples for stacked visuals.

Possible Workaround:

While awaiting an official resolution, here are some temporary solutions you may find helpful:

Leverage Custom Tooltips:
Since your DAX measure functions correctly in the tooltip, consider creating a detailed tooltip page to display the accurate market share breakdown per region. This allows users to view the correct data on hover without relying on the data labels.

Split the Visuals:
Alternatively, you can duplicate the stacked column visual and apply manual filters by year instead of using small multiples. Although this requires additional layout work, it ensures more accurate label rendering.

Use Card Visuals for Labels:
For greater flexibility, you may create separate card visuals to calculate and display market share by region and brand. While this approach is more manual, it allows full control over label placement and content.

For a long-term fix, we recommend raising a support ticket with Microsoft Power BI Support.
