Power BI Hierarchy issue

Hi I am new to Power BI and wondering if anyone can help me with an issue I am facing with hierarchies.

I have created a 2 level hierarchy (Business Unit and Division).  But when I am adding the hierarchy to a table visual, instead of showing only a single column with highest level and + sign, both columns under the hierarchy are getting displayed as separate columns.  Same is happening with another hierarchy I have created for Brand and Category.

I have tried hard to search on the forums for an answer but could not anything related to above issue.

Thanks
