Hi, I stumbled upon this also. The problem is in React-world, the unit list key should be "UnitList" with an upper "U", but the key of the response for the backend is "unitList" with a lower "u".
Until this issue is fixed I implemented a dirty hack, which transforms the response as follows:

<?php
declare(strict_types=1);

namespace App\EventListener;

use Symfony\Component\HttpKernel\Event\ResponseEvent;

class FixBrokenUnitDataListListener
{

    public function __invoke(ResponseEvent $event): void
    {
        if (!$event->isMainRequest()) {
            return;
        }

        $request = $event->getRequest();

        $route = $request->attributes->get('_route');
        if ($route !== 'pimcore_studio_api_data_importer_data_type_load_unit_data') {
            return;
        }

        $response = $event->getResponse();

        $data = json_decode($response->getContent(), true);

        if (!is_array($data) || !isset($data['unitList'])) {
            return;
        }

        $data['UnitList'] = $data['unitList'];
        unset($data['unitList']);

        $response->setContent(json_encode($data, JSON_THROW_ON_ERROR));
    }
}
