[SmartCrawl Pro] Meta title showing on actual page

After upgrading SmartCrawl to 2.2.2.6 the meta title is now showing on my pages rather than in the browser tab where they should be (and as they were in all previous versions of SmartCrawl). When I test with WP 2017 standard theme it's OK, but when I use my "normal" theme (Catalyst/Dynamik), the problem appears. Could you please let me know how I might fix this issue? Thanks. ;o)
