Hi!
It inddeed looks like some of the settings are not showing properly.
If the settings were working before, then the issue is most likely caused by a possible plugin collision. Try to deactivate the latest plugins you installed and check if it works then.
Also, try to enable debug mode in the wp-config.php file, then check the ajax search pro settings again. There should be some kind of error messages, which might help me identify the cause of the problem.
