Format change during sync slicer

Hi Team, 

I have a dashboard which has  bookmarks in it. I have slicers and wanted my slicers to reflect to all the bookmarks, also wanted the slicers to be visible. 

So I did use 'Sync slicer' option and have linked the filters to the entire report and it works fine. But during my every navigation through pages I could see a format change in my slicers. ie.. My slicers are in 'Dropdown' format but when I navigate it changes to 'List' 

Please find attached the sample for the same. Kindly suggest a way to overcome it. 

Thanks in advance
