Hierarchical Filter works when blanks are not hidden. When I hide blanks the other visuals say
Encountered invalid InvalidQueryInExpression. Values is null or empty or the expression count in one list of values does not match the expression count in Expressions
I tried this with two different hierarchies, both of which work fine with the Hierarchy Slicer.
I haven’t paid for the Hierarchical Filter yet. Just testing it on Power BI desktop.
