Cache not clearing

Everyday I make at least one post to my blog site. The cache does not clear when the posts are made. I then have to go into the Wordfence settings and do it. This happens every time even though the box is clicked in the Wordfence settings the says this “The entire Falcon cache will be cleared when WordPress publishes a post you’ve scheduled to be published in future.”

How can I get the cache to clear automatically?

Thanks.
