Gallery issue

I'm trying to share a 13x12 room and 6mb in size, nothing is in the room except for paintings on the wall but it won't work. At first it wasn't letting me save the room to my library even after restarting the game, then I checked the gallery and realized that the room has been saved I just can't share it. I tried sharing a small bedroom to test it and it worked right away so I don't understand what the problem is.
