Hierarchy slicer multi selects automatically

Hi jppp

I am using the hierarchy slicer, it works great but has some limitations which you will get in later releases when Power BI API supports custom visuals. I have an issue here if its a known one and provide me some help: 

I am using this for text column. On one of the columns when I select a particular value it auto selectes the next hierarchy as well. It works fine with other values though. When tried to uncheck the whole dashboards fails with the error. Here are the details:
