I have added different visuals one being the chiclet slicer, have it set up working fine build out various visuals for my report and if I hit undo it removes the chiclet slicer from being loaded into Power BI and that visual breaks. I have to reinstall and tell the visual it should be a chiclet slicer. When I go to reinstall it says it's already loaded, but it's not. This makes it not worth using any of the custom visuals, huge flaw!!
