Post on GridMarket not working

Can you please give information about the GridMarket Theme and Marketpress plugin. I would like to change the frontpage of Gridmarket. I do not want it to show all of my products. I know how to create a page and get it to show up as the frontpage. Settings>reading> and select a static page which in my case is frontview.

If I select frontview as my front page it works. but the problem is I would like to select pages from my post page. Under the post pages it does not show a list of my post it show the same pages for front page how do I fix this?

Do Gridmarket support changing the frontpage using another method?

How can I get a list of my post to show in the post pages instead of the post pages show pages listed in the front page?

Does Gridmarket disable all post?
