"Group by" dropdown menu is nonresponsive

I have a Zotero folder embedded using Bibbase on a LibGuides page I created, and while all of the entries are showing up properly, the "Group by" dropdown menu is not responsive on the page. It works in the editing window, but not on the public-facing side. Is there something I can do to fix this? I'd really like users to be able to reorganize the entries using my tags. This might also turn out to be a LibGuides thing, but I thought I would ask here first.
