Product page creator missing in Theme customiser (theme on trail mode)

[Bandonis]

Hi!

Im working on Shopify re-design and when testing new themes on "theme trail" mode. When customising theme there's missing "Product page". Is it possible that Shopify needs some kind of update in order for new theme work properly in ? Or this problem will solve when the theme will be activated as im working in "theme trail" mode? 

Theme customiser with missing "Product page" (products are added to store)

Theme is on trail mode, maybe this is the problem?
