Issue: Built-in slicer randomly changes from dropdown to list in PBI service

[Anonymous]

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?

It is now the end of September 2021.  I am having the same issue.

Has anyone resolved this by using a custom slicer instead?

The resolution that helped me get my stuff correct was while you are online viewing your report you will see

this in the upper right corner of your report. Click "Reset to default".

Never seen this behaviour until very recently. Yes, reset to default does fix it, but it keeps happening... Only example i have is where i have copied and sync filters to multiple pages. But only on one report! It's very annoying!
