Disappearing Walls

[gitten]

I was storing an item in Home Design and I saw my walls disappear but I don't know what I did and don't know how to get them back. Could someone tell me how to get them back. Thank you.

I got them back but have no idea what I did. So, still need an answer - thanks!!

If you tap the little orange square next to your gem total at the top of the page, you can lower the walls. Tap it again and you can raise the walls.
