Databricks newbie.

I've created a dashboard that has several widgets to allow users to select multiple values from a drop-down list.  When I first open the widget to select the values, there is a scroll bar on the right side of the box which allows me to scroll to the bottom of the list; however, it's only there for less than 3 seconds then permanently disappears unless I click out of the widget, then re-enter.  Is there a setting I'm missing to prevent this?

Thanks
