Bug iThemes Security Showing Cron Job in URL

I keep having the iThemes Security (free version) adding the Cron job in the URL

Ex: https://www.mysite.com/?doing_wp_cron=1562978104.7633941173553466796875

Then this gets picked up in Analytics. If I turn off the plugin and clear the cache, it disappears. Anyone else have this issue? How to fix it?
