Enfold not working with yoast video seo

Hi, I’ve recently finished my site with Enfold and made live http://www.davidmattock.co.uk
on my old site I was running yoast SEO and Video SEO plugins fine. So I installed them for my new enfold site and all seemed to be working fine, but I now have a problem with the video SEO as follows:

When I go to one of my portfolio entries with an embded vimeo video it seems to work fine and shows me my video thumbnail, but as soon as I enter any details like focused keyword, description etc for wordpress SEO then click update, the video thumbnail and video SEO options disappear? I’ve tried 4 different portfolio posts now and the same happens every time ?

So I contacted support at Yoast and they logged into my site and replied with the following…

“You seem to use a plugin/shortcode that we do not support ( [av_video… ).” ?

I found the support post “https://kriesi.at/support/topic/use-yoast-video-seo-with-kriesis-themes/” but does not apply to me as Im not using video in sliders just straight forward normal portfolio entries.

I think this shortcode is just part of Enfold so not sure what to do to get video SEO working now?
Many thanks
