Global Short Code issue

Not sure why this is happening, but the short code on the homepage (main site) of our Marketplace is showing many blank items with just a BUY BUTTON displayed, and it's set to show only 8 (which I would expect to be 2 rows of 4) yet it appears there are 3 pages of items, most blank.

We've already granted support access, please advise as soon as possible as the switch to MarketPress has been a major headache with many issues, both on our end and with the plugin itself, further delaying the site from going live...
