Blog Template page for new shops is breaking

I have a “New Blog Template” setup for new shops to register in the Multisite Marketplace.

I chose Gridmarket as the theme, and the instructions here:

Give directions on which items to carry over from the main site.

On the main site I’m using Studio as the theme, and so the shop template footer is breaking and trying to grab something and pull it in that doesn’t exist in Gridmarket.

How can I get the look/feel of Studio for the main portal, and use Gridmarket for the shops?
