remove button colour fill function

Hi DEngg,

Thanks for using Microsoft Fabric Community Forum.

Even though you're using a column for the button values (such as Online, Offline, and Unknown) and not a measure, the issue with conditional fill colour still occurs because Power BI buttons, especially in the Power BI Service (Fabric) -- do not always retain the proper evaluation context needed for conditional formatting. This means that even if the data comes from a column, the button may not be able to determine which specific value is selected when the report loads or when multiple selections are made. As a result, the fill colour condition either doesn’t apply or defaults to blank. Since you're using multi-selection buttons to filter visuals based on machine status, replacing them with shapes is not ideal due to the lack of interactivity and added complexity with bookmarks. A more reliable approach would be to base the button design on a fixed reference table that includes both the status values and their associated colours. This helps maintain context and ensures that the fill colours work consistently across both Desktop and the Service. Until Microsoft resolves this inconsistency in the Service, this workaround offers the best balance between functionality and appearance.

I hope my suggestions provided valuable insights. If you have any further questions, don’t hesitate to ask in a follow-up message.
