SmartCrawl conflicting with Wordfence

With Wordfence running, SmartCrawl conflicts. While in SmartCrawl I receive the message.
_______________
Background Request Blocked
Wordfence Firewall blocked a background request to WordPress for the URL /wp-admin/admin-ajax.php. If this occurred as a result of an intentional action, you may consider whitelisting the request to allow it in the future.

1). I have clicked both buttons offered 'Whitelist this action' and 'Dismiss'. Both do not work. How do I fix?
2). Is SmartCrawl even working when Wordfence is running?

Thanks,
Dean
