It appears that the list facet functionality is showing all options instead of the option groupings (Fig. 1). In the example below (Fig. 1), the 'Size Group' list facet shows all Size variants (XS, S, M, L, XL, XXL) instead of the expected groupings (Small, Medium, Large) in the facet display on the product list page. See solution here: https://cleanswift.mydwsite1.com/ (DW 9.15.9 / Swift 1.22.0) and screenshots of the facets (Fig. 1), query (Fig. 2), and index (Fig. 3) below.

Is there a step in the configuration that I'm missing, or is this a bug?
