[SmartCrawl] Title issue with Twenty Eleven

When I use SmartCrawl with the Twenty Eleven theme. The site title and tagline are appended after the title of any page.
For example, if the name of a page is "Home", the site title is "Single Test Site" and the tagline is "Just another WordPress site", the title of the page becomes "Home | Single Test SiteSingle Test Site | Just another WordPress site", but in case of other themes, it should be "Home | Single Test Site".
Note: This also happens with this theme - https://themeforest.net/item/north-one-page-parallax-wordpress-theme/8454561.
Please advice.
