Duplicated Site Description in Titles?

I didn't notice this issue in the past until now... not sure if it's a recent update that is causing it but I get duplicated site titles on my sites.

In Infinite SEO, my home title setting is "%%sitename%% | %%sitedesc%%"

What gets displayed is:

"%%sitename%% | %%sitedesc%%" | %%sitedesc%%"

I also notice that the Facebook Open Graph meta "title" tag description part is also duplicated...

For instance this is shown:

<meta property="og:title" content="Site Title | Site Description Goes Here | Site Description Goes Here" />

Nothing is wrong with the og:site_name though.

Please advise!
