Drop Down Doesn't Close

I have multiple Power BI dashboards and reports that I want to use a drop down to select a filter value, but once the user clicks on it and selects a value, it doesn't close.  It is set to single select.  Is there a configuration setting I am missing?  This "flaw" is really frustrating for my users.  Drop down or combo box controls set to single select should retract when the user selects a value.  Thank you for any insights.
