Debug cheat not working

When I type bb.showhiddne objects, everything shows up, it's all cool. When I type bb.showliveeditobjects, nothing from that category shows up. I want debug landscaping, but because of it not showing up, I have to go to the gallery. bb.showliveeditobjects has only ever worked once for me, and I don't know what went different that time. I have copy-pasted the cheats from online, and I also have typed testingcheats true, so it's not that. I would love if anyone knows what is going on and could help me fix my game!
