Problem with SmartCrawl Page title not showing with cache enabler

We have found another issue with SmartCrawl today which seems to be affecting all subsites when KeyCDN Cache Enabler plugin is used. When viewing an uncached page the correct title entered into SC is displayed but when viewing a cached page the title is the default WordPress site name and description. This is on all sites and also on Google SERP which caused a huge problem.

Sites using Yoast don't have this issue at all.

I've attached a screenshot showing the correct title, you can view the page here for that particular site to see what is output.
