Infinite SEO Plugin Removes Tagline

Hi there,

Since adding the Infinite SEO plugin on our multisite platform, the tagline for each site has disappeared from the browser-tab. The browser tab used to diaplay as follows: "Site Name | Tagline"

Now it just displays as "Sitename"

If I change the home-title in the plugin settings from "%%sitename%%" to "%%sitename%% | %%tagline%%", this still does not display properly.

Please advise on how I can make the tagline reappear on each site again.

Many thanks.
