Exhibit Sort by Year shows Relevance Button Instead

[caseyedavis12]

Describe the bug
On an exhibit where records are sorted by Date Ascending (as in Latino Empowerment: https://americanarchive.org/catalog?f%5Bexhibits%5D%5B%5D=latino-empowerment&sort=year+asc&f[access_types][]=online) the button that appears on the search results says "Relevance" rather than "Date (oldest)"

To Reproduce
Go to Latino Empowerment Exhibit. Click View All Exhibit Records. See URL where it says Sort=year+asc and then see button that says Relevance.

Expected behavior
Sort button should accurately reflect how records are being sorted.

Additional context
LOC has inquired about this twice.
