Visual composer posts shortcode not rendering

I'm having an issue with the default posts shortcode at cbd-oil.co.nz

The code is loading, but it's not pulling any actual data - as shown here: http://nimb.ws/Sx3a6P

The shortcode is just this: http://nimb.ws/NW1mT9

Everything is updated as it should be, just refuses to render properly.

Cheers for your help!
