OGP picks the wrong title

Hello,

I activated the plug-in and most times it delivers great results 🙂

However, on the following page it picks the wrong title:
http://www.salsa-trips.com/events/tags/adolfo-indacochea

instead <meta property=”og:title” content=”Hot Salsa Weekend”/>

it should pick as og:title “Adolfo Indacochea” or
<title>Adolfo Indacochea | Salsa-Trips.com</title>

Is this a bug or how can I please fix it?

Thank you 🙂
