Hi Neil,

The fix is this much code to add after including exhibit-api.js:

Exhibit.HierarchicalFacet.prototype.update = function(items) {
    this._dom.valuesContainer.style.display = "none";
    this._dom.valuesContainer.innerHTML = "";
   
    var tree = this._computeFacet(items);
    if (tree) {
        this._constructBody(tree);
    }
    this._dom.valuesContainer.style.display = "block";
};

Let me know if that works for you.

David
