When I choose the "Is any of" in the filter editor, I can easily add values via the + icon. However, I can't delete a value from the clause after it's added. Deleting the value still leaves the actual item, but with ''. I have to delete the entire filter with the X icon and completely re-do it. There should be an X icon to delete/remove the values from the Is Any Of statement or a right click delete. How to delete just one value? This would be a great enhancement!
