Display only alternate labels on advanced search page

On our current advanced search page, the field labels are displaying as ‘default (alternate)’ so ‘Creator (Composer)’ for example. We want to just display the alternate label.

We are building a custom version of the center row theme and I can edit the resource-template-restrict.phtml file but I am not sure what to change to isolate and display just the alternate label value.

There’s no setting to omit the original label. I suppose you could modify the code in Omeka\Form\Element\PropertySelect::getValueOptions() so that

if ($altLabels) {
    $valueOptions[$propertyId]['label'] = implode(', ', $altLabels);

This worked. Thanks!
