This is a video how it works at my test setup with all plugins deactivated.
It’s definitely not related to URE. I can just suppose that something is wrong with your installation.
You can send to suport [at-sign] role-editor.com a download link to your test installation database backup. I will try to repeat this issue at my local test environment, where I can debug it (if it will be repeated) to isolate a reason. Send me your test wp-config.php also.
