Okay, I figured out that if you place a sign on the edge of a cloud, and place a cloud on top of it with a mannequi, you won't be able to read what's written on the sign... If you remove the cloud, you can't read what's on it either... You can only read if you remove the mannequin.
I guess it just gives priority to the higher block that has a commend in it and since you're not owner it can't show you the edit manequin so it's just not showing anything...
