Need help using new blog templates to create new shops!

Multisite; MarketPress; Pro3 theme; New Blog Templates.

Failed to create new shops using https://artcommons.ca/shop-template as the "ArtCommons Shop Template" default.

Shop-template content is on screen.
Pro3 Theme is not activated.
Do not have site admin role to access wp-admin.
WP Site links have /shop-template//shopdemo2.
If I get into shopdemo2/wp-admin, layout is not WP as usual - it is off.

Thank you.
