Wrong author in my Twitter Cards



I don’t understand why my Twitter Card do not have the good author in the Twitter timeline : it should be @FranceLive instead of Heather Francell @heatherartworks ?
Here is our timeline : https://twitter.com/francelive

It is very weird because when we open a tweet, the good author @francelive is displayed :

Les résultats du 1er Tour à Paris – Municipales 2014 http://t.co/Ioagj51j7v

— France Live (@FranceLive) 24 Mars 2014
What's wrong ?

Thanks for your help.
