You have to double click on each file that you want to extract within the popup to add it to your pack. Hit ok and it should take you to your mod with that table. You should never be able to get the entire pack, and even if you did, it should show up as a mod in the manager
EDIT
Wait...
No popup?
I think I know whats happening here. You've created a new pack, not a new "my mod" so it doesn't have the extraction processes. This is the "new" referred to in step 1.
EDIT2
See if those extra pictures help
