problem with MC Edit and powered pistons and redstone lamps

i powered a piston with a torch, i went into MC Edit and copied and pasted it and when i got back the piston base was gone. after trying to put a block on top of the piston it disappears. i don't know if there is a forum for MC Edit or not. (in the picture the torches are below the pistons) and after copying and pasting the torches go away and are deleted.
