framemarket parent theme missing?

Hello, first time posting here as I was always able to find answers from existing threads.

I am currently using latest WP & BP with multisite enabled.
I just installed framemarket theme to my appropriate server folder and encountered a problem.
(FYI: Yes, I got the gridmarket folder out of framemarket/theme folder and placed both folders into my server)

Problem: as a network/super admin, I go to network enable gridmarket theme in network admin and I cannot find girdmarket theme to enable under themes.

Any ideas?
Thank you.
