Broken admin page question

Hi

The checkboxes are broken on the admin page and tracking down the code, the PHP code is like:

<?= ($allow_admin_ve_privacy_levels) ? 'checked' : ''; ?>

In the context of :
buddypress-activity-privacy/includes/bp-activity-privacy-admin.php

The <?php is not complete.

like:

<input id="allow-admin-view-edit-privacy-levels" name="allow-admin-view-edit-privacy-levels" <?= ($allow_admin_ve_privacy_levels) ? 'checked' : ''; ?> type="checkbox" />

I checked out the Github and older versions of this plugin, and the code is done in this way on any versions.

So, is this a PHP issue of PHP versions/ installed modules or what?

Never seen this before….
