I have report where mulitple slicers are created on different pages with same fields, using built-in slicer in Power BI Desktop. The type is set to 'dropdown' from slicer header. This reflects correctly on Power Desktop every time. But, when published to Power BI service, sometimes it randomly changes the type to list from dropdown. When that report page is reset or the web page is refreshed, it then shows correct visual i.e. slicer with dropdown type. There is no apparent reason for this to be happening. Is this a possible bug?
