🎩 Description

Hey!
Inspecting a participatory process presentation page's html we can see that the title is displayed twice in the twitter and facebook meta data attribute.

Here is the page I used : http://staging.decidim.codegram.com/processes/suphorta
And here is the mata data attribute for the page
<meta name="twitter:title" content="Superilla Horta - Superilla Horta - City and Me">
<meta property="og:title" content="Superilla Horta - Superilla Horta - City and Me">

The problem is that it generates snippets on social media with this error :

Any idea how to fix this ?
