Webform 'show in filter' throwing an error

In v14, I have a webform created and have added the desired fields to it. I’d like to have a status filter at the top of the list view so I checked the ‘Show in filter’ box inside the web form field configuration. After this, a filter does show up in the web form but it’s non-functional. The following error shows in the browser console:

filters.append((d.fieldname, "in", allowed_docs))
TypeError: 'NoneType' object is not callable
