[Smush Pro] Issues with styling of backend after update WP Smush Pro version 3.2.4

After updating to WP Smush Pro version 3.2.4., the backend dashboard styling is gone. I have removed every other plugin as well as changed themes and cannot find the culprit. I do know that the actual wp-smush.php file is where the issue is. If I swap this file with the older one's, the styling is all back to normal, but of course that downgrades it as well. Any thoughts?
