Share description not consistant

Hi
I cannot figure out why the shared meta descriptions work on some pages but not others.

I am using yoast seo plugin as well.

this page: http://forestnation.com/fundraising/
Works perfectly. The meta description for that page is exactly what I have entered in the yoast seo meta description book. And it matches the source code.

this test page: http://forestnation.com/barcelona-lujo/
The source code shows the yoast seo meta description correctly. But the facebook shared description is a general one and the thumbnail isn’t an image on the page.

I have cleared caches and checked all configurations I can think of.

Any ideas would be great.

Thanks
