Shortcode grey buttons

Hi,

thanks for the great plugin!

I am using the shortcode to embed the buttons. I have chosen the grey design for the buttons, but they are showing in their default design if embedded via shortcode.

I suppose, I have to specify the design in the shortcode?!
How would I do this?

PS: If embedded via the general embded option they show up grey.

regards, Oliver
