I am using the latest update of Power BI (Jan 2017) with a slicer that I want to use to filter by month (hiearacy level 1) and then week starting (level 2). However when I try to import the hiearchy slicer custom visual it says it is already in use in my report.
When I try to delete a custom visual I cannot see it in the list:
When I click import and try to import the latest version of the custom visual (HierarchySlicer.0.7.9.pbiviz) I get this message.
Clicking update does not change or add the visual in the report.
