How to install Laundry Day stuff properly?

I installed the Jungle Adventures pack thinking that the Laundry Day stuff was included but I didn't know it's not (but it still shows I "own" the pack somehow without any of the items) I downloaded Laundry day and installed it but all of my Jungle Adventures stuff went missing. How do I install it properly? Thanks!

You installed Jungle then Laundry so to get things right install Jungle again.
