Filters build themselves from the people in the section, and only appear when all of these are true:
- Show filters is on in the Team grid.
- The section shows more than three people.
- The field has at least two different values. If everyone is a Stylist, there is no Role filter to show.
In collection mode, also check that the Namespace and keys under Metafield keys match your definitions exactly (custom and role, location, level by default), that the definitions have storefront access on, and that the values are spelled consistently: Downtown and Downtown Salon are two entries.
If the team is on more than one page, raise Experts per page above the team size so the filters cover everyone. More in Filters.
