Thank you for your report. I think I just fixed this issue

It now correctly has an installation target, but still thinks it's a game. The copper pack shows up as "A collection of assets" instead of "A game".
I believe this is because of the category, the copper pack is in the "assets" category. This pack isn't in the assets category however, it seems it doesn't have one at all
