Missing Product Short Description - Woocommerce Element problem

Hi,

I have a problem with the short description disappearing from view on a mobile device or narrow view when the woocommerce element is active in GP Premium.

All updates have been run and browser cache cleared. If i de-activate the plugin then the short description re-appears albeit in a long thin line.

But when the element is active - if completely disappears again.

Ideally i would have the short description drop below the image on narrow view.

Thanks
Simon
