My matress for bunk beds doesn't work!

So, I downoloaded pixeldreamworld's bunk bed and zero footprint matress: pixeldreamworld.tumblr.com/post/156411968190/functional-toddler-bunk-bed-frame-zero-footprint

I tried to insert the matress on top bunkbed using moveobjects on as the creator of the bunkbed, pixeldreamworld suggested. But that didn't work. So, I tried to fix that. I found out that using bb.moveobjects on cheat on matresses doesn't work anymore and that you need to lift them up manually in blender from now on.

I followed this tutorial: sims4studio.com/thread/19719/removing-footprints-mattresses

But when I tested it in the game, it didn't work. Basically, when I tried to make my toodler sim sleep on the top bed, she basically slept on the bottom bed:
